If a solution has a ph of 75 what would its new ph be if, Ask an Expert

Academics

If a solution has a pH of 7.5, what would its new pH be if the concentration of H₃O ions in the solution were increased by 100 times? Explain your reasoning.

As a tenfold increase in H₃O ion concentration reflects a decrease of one pH unit, a 100-fold enhance in concentration reflects a reduces of two pH units. Thus, the new pH would be 5.5.
