1. What property of NaOll becesvitates that we shandenfice an NaOH wolution wiine a primary sandard sech as Kui?? 2. Look op the molecular weight for potassium hydrogen phthalate (KIIP) and deternine the number males of KHP in 0.409g of KHP. 3. The 0.409g of KHP is dissolved in 100mL of deionized water in an Erlenmeyer Eack. Three drops of phenolphthalein indicator are alded and the solution is titrated widi NaOH (aq) to the faint pink endpoint. A sapahot of the burette before (lefi) and after inght) die tiration is shown. Cakculate the concentration of the NaOH (aq) titrant. Read the burente to the neares 005mL incroment. 4. A 10.0mL sample of inknown HC (aq) is tramoferal to an Erlenmeyer fack alone with 90mL. of deionized water and 3 drops of phenolphahalein incisator. The solution is titrated to the faint pink endpoint with 15.20mL. of the same NaOH (aq) solution used in problem 3. Calculate the concentration or HQ (ap) in the original 100 mL sample. 1.
