Question

What is the ph for a 0.05m solution of hydrocholoric acid ?

Answer 1

Answer:

it's a strong acid and it fully dissolves This solution can be considered equivalent to a solution 0.1 M (0.15 - 0.05) in HCl thus pH = -Log (0.1) = 1.

Answer 2

Explanation:

From this table of activity coefficients 5m HCl has an activity coefficient of 2.38, so activity is 11.9, which yields pH = -1.1.
