Question

if ph of a solution is 2, the molarity of solution is...​

Answer 1

Answer:

The molarity of hydrogen ions in the solution (pH=2) is 0.01M

Explanation:

Given that,

pH of solution = 2

the relation between pH and molar concentration of H⁺ ions is,

           pH = - log [H⁺]

⇒           2 =  - log [H⁺]

   log [H⁺] = - 2

⇒      [H⁺]  =  10⁻² = 0.01 M

Hence, the molarity of H⁺ ions is 0.01 M.
