If a muriatic acid solution has a ph of 2.50, what is the hydronium ion concentration (hydronium ion concentration is also the muriatic acid concentration)?

with a ph of 2.50, the hydronium ion concentration is

[H₃O⁺] = 0.032 M

Explanation:

The acidity of a solution is measured by its pH, which is the logarithm of the inverse of the molar concentration of hydronium (H₃O⁺) ions:

pH = log 1 / [H₃O⁺] = - log [H₃O⁺]

When you know the pH value you can find hydronium concentration using the antilogaritm function:

The unit of molar concentration is M.

To prove your answer you can take the logarithm of 0.0316:

log (0.0032) ≈ 2.500

Evaporation: this is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). water vapour droplets join together to make clouds! condensation: this is when water vapour in the air cools down and turns back into liquid water.
