Answer:
it will increase 100 times.
Explanation:
pH is calculated by taking negative log of hydronium ion concentration.
pH = -log[H⁺]
So let initial pH of solution is 4 then the [H⁺] = 10⁻⁴
if the pH decreased by 2 it means that the [H⁺] = 10⁻²
Thus the new [H⁺] is 100 times more than the initial [H⁺] .
The pH decreases with increase in concentraiton of pH is calculated by taking negative log of hydronium ion concentration.
pH = -log[H⁺]
So let initial pH of solution is 4 then the [H⁺] = 10⁻⁴
if the pH decreased by 2 it means that the [H⁺] = 10⁻²
Thus the new [H⁺] is 100 times more than the initial [H⁺] .
