Explanation:
The Common-Ion Effect in Acid-Base Equilibria 1. a) Determine [H3O+] and [F-] in 0.500 M HF. Ka HF = 6.6 x 10-4 b) Determine these concentrations in a solution that is 0.100 M HCl and 0.500 M HF. Ka HF = 6.6 x 10-4 2. Calculate [H3O+] and [COOH-] in a solution that is 0.100 M HCOOH, formic acid, and 0.150 M NaCOOH. Ka HCOOH = 1.8 x 10-4
