please answer from question a-j

40.00mL of a 0.1000M carbonic acid (H2CO2) was titrated with 0.1000M calcium hydroxide. a) Sketch a graph of the titration, labelling the weak acid, weak base, buffer regions, points at which pH=pK, equivalence points, half-equivalence points, and excess HOor excess OH. Indicate if the resulting solution will be acidic, basic, or neutral at the second equivalence point (paper only) b) Calculate the volume of sodium hydroxide required to reach the first equivalence point. Vn= Answer mL c) Calculate the volume of sodium hydroxide required to reach the second equivalence point. Vu= Answer mL d) Write the balanced acid-base reaction (paper only) and calculate the pH before the addition of sodium hydroxide. pH Answer e) Write the balanced acid-base reaction (paper only) and calculate the pH after the addition of 10.00mL of sodium hydroxide pH Answer f) Write the balanced acid-base reaction (paper only) and calculate the pH after the addition of 20.00mL of sodium hydroxide pH Answer g) Write the balanced acid-base reaction (paper only) and calculate the pH after the addition of 29mL of sodium hydroxide pH Answer h) Write the balanced acid-base reaction (paper only) and calculate the pH after the addition of 40mL of sodium hydroxide pH Answer j) Write the balanced acid-base reaction (paper only) and calculate the pH after the addition of 44mL of sodium hydroxide pH
