Calculate the pH of solution when 100 mL, 0.1M CH 3 COOH and 100 mL, 0.1M HCOOH are mixed together. (Given: K a (CH 3 COOH) = 2 x 10 -5 , K a (HCOOH) = 6 x 10 -5 )
Text Solution
Verified by ExpertsThe correct answer is:
2
2.7
As the volume is doubled, concentration would be half. The total [ H + ] is obtained by addition of [ H + ] from both acids.
=2x10 -3
pH=2.7
