Answer the questions below with the data provided: 15 mL of 5% NaOH (w/v) is used to deprotonate the unknown carboxylic acid. The TBME is washed with an additional 10 mL of the NaOH solution and then 20 mL of water which are all combined. later, 10 mL of 6.00M HCl was used to protonate the carboxylate ion. Assume the concentration of carboxylate is negligible.
A) After the carboxylate is protonated, how many moles of HCL are left in excess?
B) What is the solution's final H+ ion concentration?
C) What is the pH of the final solution?
