Question

Calculate the [H+] in a solution that has the following pH:

Answer 1

Answer:

1.) [H⁺] = 2.69 x 10⁻⁹

2.) [H⁺] = 6.61 x 10⁻⁶

3.) [H⁺] = 5.01 x 10⁻²

Explanation:

The [H⁺] in a solution can be found using the following equation:

[H⁺] = 10^(-pH)

Therefore, you can plug the given pH into the equation and solve for the hydrogen ion concentration ([H⁺]).

1.) pH 8.57

[H⁺] = 10^(-pH)

[H⁺] = 10^(-8.57)

[H⁺] = 2.69 x 10⁻⁹

2.) pH 5.18

[H⁺] = 10^(-pH)

[H⁺] = 10^(-5.18)

[H⁺] = 6.61 x 10⁻⁶

3.) pH 1.30

[H⁺] = 10^(-pH)

[H⁺] = 10^(-1.30)

[H⁺] = 5.01 x 10⁻²
