Question

Acetic acid dissociate 1.3%.what will be the pH of N/10 solution of the acid

Answer 1

Answer:

2.88

explanation:

we have N/10 or 0.1 N of CH3COOH which dissociate only 1.3%.

1.3%of 0.1 N CH3COOH is dissociated, which means 1.3 percent of 0.1 N H+ is formed.

1.3 % of 0.1 means 0.0013 N H+ is formed.

$pH=-logH^+\\pH=-log(0.0013)\\pH=2.88$
