Expert Answer

Step 1

Given that,

Mass of acetic acid = 0.1 M

Volume of acetic acid= 25mL

Mass of KOH = 0.1 M

Step 2

A: when 0.00 mL of KOH is added

Firstly we calculate the mole

Step 3

B: When 12.5mL of KOH added

Mole of acetic acid = 2.5 mole

Mole of KOH = 1.25 mol

1.25 moles of both w...
