A chemist is using a solution of HNO₃ that has a pH of 3.75. what is [H⁺] for the solution is 1.7 × 10⁻⁴M.
Concentration of H⁺ ion will be calculated by using the below equation of pH as:
pH = -log[H⁺]
or [H⁺] = [tex]10^{-pH}[/tex]
Given that, pH = 3.75
So concentration of H⁺ ion will be calculated as:
[H⁺] = [tex]10^{-3.75}[/tex]
[H⁺] = 1.7 × 10⁻⁴M
Hence concentration of H⁺ ion is 1.7 × 10⁻⁴M.
