Determine the hydronium ion concentration in a solution that is 0.00014 M HCl.

Answer in units of M.

1.4 * 10⁻⁴ M

Explanation:

Molarity (M) is the concentration of a solution expressed as the number of moles of solute per liter of solution:

Molarity (M) = moles of solute / liters of solution

Hydrochloric acid dissociates by the equation:

HCl = monoprotic acid, thus the concentration of the acid is the concentration of the hydronium ion.

[H⁺] is the hydrogen ion concentration in terms of molarity

[H⁺] is called hydronium ion.

HCl conc = 1.4 x 10⁻⁴ M

[H⁺] = 1.4 * 10⁻⁴ M
