1a. How many mL of (6.3800x10^-1) M HCOOH would it take to reach the equivalence point in the titration of (4.8600x10^1) mL of (4.72x10^-1) M KOH?
1b. What is the pH at exactly 1/2 of the volume required to reach the equivalence point in the titration of (4.640x10^1) mL of (4.140x10^-1) M HCNwith (6.54x10^-1) M KOH?
Please help, will rate.
