Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

Which solution could be added to 100.0 mL of 0.500 M HCH3COO to
produce a buffer? Select all that apply.
100.0 mL of 0.400 M KCH3COO
125.0 mL of 0.500 M KOH
75.00 mL of 0.500 M NaOH
125.0 mL of 0.500 M NaCH3COO

Expert Solution

Step 1

Volume of CH₃COOH = 100.0 mL or 0.100L

Molarity = 0.500 M
