What is the hydroxide ion concentration for muriatic acid (has a ph of 2.5)?

The concentration of the hydroxide ion concentration for muriatic acid is 3.16 * 10^-12 M

Explanation:

Muriatic acid = HCl

pH = 2.5

pH = -log[H+]

pOH = 14 - pH

pOH = 14 - 2.5 = 11.5

pOH = -log [OH-]

11.5 = -log [OH-]

[OH-] = 10^-11.5

[OH-] = 3.16 * 10^-12 M

The concentration of the hydroxide ion concentration for muriatic acid is 3.16 * 10^-12 M
