As concentration increases by a tenth, what happens to the ph?

As the concentration of a solution, will increase by a tenth, the hydrogen ion concentration can become basic. The hydrogen ion concentration measures how acidic or basic the substance is, wherever zero is that the most acidic because of increase in H+ during a concentration, fourteen is that the most simple as a result of low H+ concentration and seven is taken into account neutral with an equal range of H+ and OH- ions.

Explanation:

pH may be a measure of the hydrogen particle concentration of a solution. Solutions with a high concentration of atomic number 1ions have an occasional hydrogen ion concentration and solutions with occasional concentrations of H+ ions have a high hydrogen ion concentration.

For a neutral solution, pH=7
Acidic solutions pH<7 
Basic solutions have pH>7

The lowers the pH, a lot of acidic the solution and therefore the higher the concentration of H+.
