Answer to Question #252858 in Chemistry for Dolce.nightsky

Question

A photographic "stop bath" contains 160mL of pure acetic acid. HC2H3O2(1) in 650 mL solution. What is the v/v concentration of acetic acid in the stop bath?

Answer 1

Solution:

acetic acid = HC₂H₃O₂ - solute

Volume of acetic acid = 160 mL

Volume of the solution = 650 mL

v/v concentration = (solute volume / volume of the solution) × 100%

v/v(HC₂H₃O₂) = (160 mL / 650 mL) × 100% = 24.6%

v/v(HC₂H₃O₂) = 24.6%

Answer: The v/v concentration of acetic acid is 24.6%
