Question

If the molar concentration of H3O+ is 1.0 x 10-1, the pH is ___ and the solution is ____

Answer 1

The pH of a solution with a molar concentration of H3O+ at 1.0 x 10^-1 is 1, making the solution acidic.

Step-by-step explanation:

If the molar concentration of H3O+ is 1.0 x 10-1, we can calculate the pH using the formula pH = -log[H3O+]. Plugging in the concentration, we find:

pH = -log(1.0 x 10-1)

pH = 1

Since the pH is lower than 7, this indicates that the solution is acidic. Thus, if the molar concentration of H3O+ is 1.0 x 10-1, the pH is 1 and the solution is acidic.
