Question

What is the hydrogen ion molarity of a solution with a pH of 10.16

Answer 1

The hydrogen ion molarity : 6.918 x 10⁻¹¹ M

Further explanation

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.

pH = - log [H⁺]

So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.

A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.

pH of solution = 10.16

the [H₃0⁺] of the solution :

`\tt pH=-log[H_3O^+]\\\\10.16=-log[H_3O^+]\\\\(H_3O^+]=10^(-10.16)=6.918* 10^(-11)`
