Hydrochloric acid solution (HCl)。
Balance.Graduated cylinder.Procedure:1. Preparation of Standard NaOH Solution:Weigh out approximately 0.4 grams of NaOH on a balance.Dissolve the NaOH in a 250 mL graduated cylinder with distilled water.Transfer the solution to a buret.2. Preparation of Unknown HCl Solution:Pipet 25 mL of the unknown HCl solution into an Erlenmeyer flask.Add 2-3 drops of phenolphthalein indicator to the flask.3. Titration:Fill the buret with the standard NaOH solution.Record the initial volume of NaOH in the buret.Slowly add the NaOH solution to the HCl solution in the Erlenmeyer flask, swirling the flask constantly.Continue adding NaOH until the solution turns a faint pink color.Record the final volume of NaOH in the buret.4. Calculations:Calculate the number of moles of NaOH used:Moles of NaOH = (Final Volume Initial Volume) x Molarity of NaOH.Calculate the number of moles of HCl present in theunknown solution:Moles of HCl = Moles of NaOH.Calculate the concentration of the unknown HCl solution:Concentration of HCl = Moles of HCl / Volume of HCl.Strong Acid-Strong Base Titration:Materials:Buret.Pipet.Erlenmeyer flask.Phenolphthalein indicator.Sodium hydroxide solution (NaOH)。
