# How many times more basic is a pH of 12 compared to a pH of 8?

##### 1 Answer

10000 times more basic

#### Explanation:

Since pH is a logarithmic scale, a change in pH of 1 results in a ten-fold change in the concentration of **ten-fold change in acidity/basicity** . This is because how acidic/basic a substance is can be determined by the **concentration of hydrogen ions.** The more

You can calculate the concentration of

So for a pH of 8, we get

For a pH of 12, we get
