Question

Given the concentration = 5.0x10⁻2, calculate the hydrogen (H+) ion concentration.

a) 5.0x10⁻2
b) 2.5x10⁻2
c) 1.0x10⁻2
d) 1.0x10⁻4

Answer 1

The hydrogen ion concentration is 5.0 x 10^-9 M.

Step-by-step explanation:

To calculate the hydrogen ion concentration, we can use the formula [H3O+][OH-] = 1.0 x 10^-14 at 25 °C. Since [OH-] is inversely proportional to [H3O+], we can rearrange the equation to solve for [H3O+]. In this case, the concentration of [H3O+] is 5.0 x 10^-9 M.
