The pka of hypochlorous acid is 7.530. a 52.0 ml solution of 0.149 m sodium hypochlorite (naocl) is titrated with 0.293 m hcl. calculate the ph of the solution
Answers: 1
![pH=pK_a+log(\frac{[conjugate base]}{[weak acid]})](/tpl/images/0604/0490/b03d4.png)
![pH=pK_a+log(\frac{[conjugate base]}{[weak acid]})\\pH=7.53+log(\frac{0.149M}{0.293M})\\pH=7.53-0.2937\\pH=7.236](/tpl/images/0604/0490/9ca36.png)
