Question

The Ph of 0.004 M hydrazing Solution is 9.7 calculate the hydrogen ion concentration?

Answer 1

the hydrogen ion concentration [H⁺] = 2 X 10⁻¹⁰

Explanation:

Given

molarity = 0.004 M

pH = 9.7

[H⁺] = ??

Solution

pH = - log [H⁺]

[H⁺] = antilog (-9.7)

[H⁺] = 2 X 10⁻¹⁰

the hydrogen ion concentration [H⁺] = 2 X 10⁻¹⁰
