# Question #ae736

##### 1 Answer

#### Answer:

An increase in pH means that the solution is becoming less acidic and more basic.

#### Explanation:

pH means parts Hydrogen. It is a measure of the concentration of Hydrogen ions in the solution.

pH is the negative log of the hydrogen ion concentration.

pH =

Since pH is the negative log it means that the lower the pH the more acid the solution is

Example if the solution is 10% ( 10/100) or .1

1 =

The log is the exponent of the hydrogen ion concentration so the log is -1 but pH is the negative log so

Example if the solutions is only 1% ( 1/100) or .01

2 =

So as the pH number goes up in value the hydrogen ion concentration goes down, and the solution becomes less acidic.
