Question #114772
What is the pH of an aqueous solution having a hydronium-ion concentration of 6.83 × 10-3 mol/L? Is the solution acidic or basic?
Expert's answer
According to the definition:
pH = - log[H3O+]
where [H3O+] - concentration of hydronium ions.
As a result:
pH = -log(6.83 × 10-3) = 2.17
As pH < 7, the solution is acidic.
