Is a solution in which (OH) = 1.0 10-1M acidic, basic, or neutral?

The pH is 13,00 and the solution is basic.

Explanation:

The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and higher than 7 to 14 basic. It is calculated as

pH = - log (H 30+)

Both pH and pOH have a relationship to belonging to the same aqueous solution: the expression of the Kwater (ionic product of the water Kw) is used:

[H3O ^ + ]x [OH ^ - ] = 1x 10 ^ - 14

[H3O ^ + ]x [1.0 10-1]=1x 10 ^ - 14

[H3O ^ + ] = 1x 10 ^ - 14/1.0 10-1M = 1.0 10-13 M

pH = - log (H 30+) = - log (1.0 10-13 M) = 13, 00

As the pH value is higher than 7, it corresponds to a basic substance.
