Glycolic acid, HOCH;COOH, which is a monoprotic acid and a constituent in sugar cane, has aРКa of 3.83. A 25.0 mL solution of glycolic acid is titrated to the equivalence point with 36.0 mL of 0.020 M sodium hydroxide, NaOH, solution. a) Write a balance chemical equation for the neutralization of HOCH2COOH with NaOH What is the concentration of the initial Glycolic acid solution? b) Write the predominate acid base equilibria for the initial HOCH;COOH solution What is the initial pH of the initial 25.0 mL Glycolic acid solution? (Hint: construct an i,c,etable) c) What is the pH of the titration when only 18.0 mL of sodium hydroxide was added?(Hint: what kind of solution is it? i.e. detailed calculation NOT needed! d) Write the predominate equilibria at the equivalence point of the titration. What is the pH of the resulting solution at the equivalence point of this titration?(Hint: construct an i,c,e table for the diluted solution) e) Write the predominate equilibria for the 0.020 M NaOH titrant solution What is the pH of this titrant solution?
