Y2K
The year that many computers may develop problems because of lack of foresight on the part of programmers .In the 1980s and before ,most computer programs were designed to store only the last two digits of the years on all dates .When the Year 2000 comes ,these programs will show dates of 00,which maybe interpreted the same as 1900.This discrepancy may cause widespread problems ,especially in the large computer systems used in government and big industries.

《分析化学》阅读材料03 摘自Analytical Chemistry (FECS) ●In the Br?sted-Lowry theory, an acid is a proton donor and a base is a proton acceptor. Each acid is related to its conjugate base and vice versa: Acid = base + proton Therefore, the conjugate base of a strong acid must be a weak base and the conjugate base of a weak acid must be a strong base. Together they form a couple, and an acid without its conjugate base is a meaningless concept. In order to release a proton, the acid must find a base to accept it. In an aqueous solution, the proton, H+, having an extremely small ionic radius, cannot exist as such. It is hydrated, forming the hydronium ion H3O+ and higher hydrates. Thus, an acid-base equilibrium is not a simple dissociation equilibrium, but the result of a proton transfer reaction in which there are at least two reagents and two products. Such a process is also called protolysis. The overall reaction is expressed by: HX + H2O = H3O+ + X-. The overall equilibrium constant is K = [H3O+][X-]/[HX][H2O]. The acid dissociation constant Ka is given by: Ka = K[H2O] = [H3O+][X-]/[HX]. Ka reflects not only the acid strength of HX, but also the base strength of water. This why different acid dissociation constants are observed for the same acid in different solvent. ●Similar proton transfer reactions exist in all solvents possessing proton donor and acceptor properties. Proton transfer reactions are extremely fast. This makes them very suitable for analytical applications and acid-base reactions have found wide use in volumetric methods and other analytical techniques. ●The pH value is a measure for the acidity or basicity of a solution, aqueous or nonaqueous. ●Acid-base indicators are chemical substances with acid-base properties, having different colors in their protonated and deprotonated forms. ● A most important application of acid-base systems is related to the property of such a system to act as a buffer. Many chemical reactions produce protons (in aqueous solutions hydroniums) or hydroxide ions. If these products remain in the system, a corresponding pH change is observed. However, if a buffer is present in the solution it reacts with the liberated hydrogen or hydroxide ions so that only a relative small change of pH occurs. Buffer consist of a mixture of a weak acid and its conjugate base. The most efficient buffer for a given pH consists of a 1:1 ratio of the protonated and deprotonated forms of a weak acid (with pKa = pH). This cannot always be achieved, but if we wish to prepare a solution of a certain pH, we select a weak acid with a pKa value close to the desired pH. Buffer solution resists changes in pH upon adding of strong acids or strong bases. Depending on the relative concentrations of the acid and base forms of the buffer, the system can resist small or large additions of strong acid or base. This buffer capacity is defined as the number of moles of strong acid of base required to change the pH of 1 L of buffer solution by one pH unit. Solutions with high or low pH values, formed as a result of dissolution of large quantities of a strong base or acid, are characterized by a large buffer capacity, although the electrolyte practically consists of only one of the conjugate forms (e.g., HCl or NaOH solutions). ● A general requirement for all volumetric methods is that the titration process is fast and that it proceeds in a definite stoichiometric ratio, the endpoint of the reaction must by easy to detect and the reaction should be specific and not influenced by other constituents of the solution, i.e., there should be no interference. Question: 1. A H3PO4 solution is brought to pH = 7.00 by the addition of NaOH. Calculate the concentration of the various forms of orthophosphate if the total phosphate concentration in buffer is 0.200 mol /L. pKa1 = 2.16, pKa2 = 7.21, pKa3 = 12.32. 2. A buffer solution is prepared from acid, HA, Ka = 5 10-5, and its salt. The concentration of HA in the buffer is 0.25 mol / L. To 100 mL of the buffer added 5.0 mmol of NaOH, and the pH of the resulting solution is 5.60. What was the pH of the original buffer? 3.It is desired to change the pH of 100 mL of 0.100 mol / L HCl from 1.00 to 4.40 by the addition of sodium acetate, CH3COONa3H2O. How much solid sodium acetate salt must be added in grams? Assume no volume change for the solution as the result of the addition. 4.What is the buffer capacity of a solution which is 0.100 mol / L of NH3 and 0.200 of NH4Cl? 5.Calculate the pH of each of the following solution: (a) Water in equilibrium with CO2 of the air; pKa1 = 6.38, pKa2 = 10.25. (b) Water as in part (a) brought to pH = 7.00 with NaOH and allowed to regain equilibrium with CO2. 6. Derive the following expression for the pH at the first stoichiometric point in the titration of a mixture of two weak acid: HA, the stronger, Ka1, concentration C1; HB, the weaker, Ka2, concentration C2: pH = 1/2 (pKa1 + pKa2) – 1/2 lg (C1/C2)

The second is the Great Sphinx of Giza, a sculpture with the body of a lion and the head of a man, which stands 20 meters tall and 73 meters long. The origin of the Great Sphinx of Giza goes back 5,000 years, Although many sphinx sculptures have been found over the years, researchers believe that the Great Sphinx which guards the pyramids in Giza was actually the first one to be made (around 2600-2500B.C.). The head of the Sphinx represents Khafre, the Pharaoh who ruled Egypt at the time. About two thousand years later, around 570 B.C., sand had covered all but the head of the Great Sphinx. The people living in the area had forgotten the history of the statue, so they imagined that the head represented the sun god Ra and began worshiping it. The son of Pharaoh Amenhotep II heard the head speak to him in a dream. The Sphinx’s head made him promise to clear the sand from the statue’s body. The son, Thutmose, kept his word and did what he was told in the dream. He also built walls around the statue to prevent the sand from covering it again. After all of the sand was cleared away, Thutmose made a large stone tablet that told the story of his dream. He placed this tablet between the two front feet of the Sphinx, where it stands to this day. For hundreds of years, the Sphinx attracted people both as a religious monument and as a work of art. But eventually, the desert sand once again covered the Sphinx, leaving only

UNIT 1 一、材料根深蒂固于我们生活的程度可能远远的超过了我们的想象，交通、装修、制衣、通信、娱乐（recreation）和食品生产，事实上（virtually），我们生活中的方方面面或多或少受到了材料的影响。历史上，社会的发展和进步和生产材料的能力以及操纵材料来实现他们的需求密切（intimately）相关，事实上，早期的文明就是通过材料发展的能力来命名的（石器时代、青铜时代、铁器时代）。 二、早期的人类仅仅使用（access）了非常有限数量的材料，比如自然的石头、木头、粘土（clay）、兽皮等等。随着时间的发展，通过使用技术来生产获得的材料比自然的材料具有更加优秀的性能。这些性材料包括了陶瓷（pottery）以及各种各样的金属，而且他们还发现通过添加其他物质和改变加热温度可以改变材料的性能。此时，材料的应用（utilization）完全就是一个选择的过程，也就是说，在一系列有限的材料中，根据材料的优点来选择最合适的材料，直到最近的时间内，科学家才理解了材料的基本结构以及它们的性能的关系。在过去的100年间对这些知识的获得，使对材料性质的研究变得非常时髦起来。因此，为了满足我们现代而且复杂的社会，成千上万具有不同性质的材料被研发出来，包括了金属、塑料、玻璃和纤维。 三、由于很多新的技术的发展，使我们获得了合适的材料并且使得我们的存在变得更为舒适。对一种材料性质的理解的进步往往是技术的发展的先兆，例如：如果没有合适并且没有不昂贵的钢材，或者没有其他可以替代（substitute）的东西，汽车就不可能被生产，在现代、复杂的（sophisticated）电子设备依赖于半导体（semiconducting）材料四、有时，将材料科学与工程划分为材料科学和材料工程这两个副学科（subdiscipline）是非常有用的，严格的来说，材料科学是研究材料的性能以及结构的关系，与此相反，材料工程则是基于材料结构和性能的关系，来设计和生产具有预定性

Thefrog feels surprised (惊讶)and says, “The sky is only as bigas the mouth of the well. How do you fly from the sky?” The crow says, “The skyis very big. You always stay in the well, so you don't know the world is big.” Thefrog says, “I don't believe (相信).”But he crow says,“ Youcan come out and have a look by yourself.” So the frog comes out from the well.He is very surprised.
