Unit 4 Lesson 20

Dilution

This means that 8 is ten times more basic than 7 is one hundred times more acidic than 7.

You can add water to a solution to dilute it.

• In an acidic solution, adding water increases it's pH closer and closer to 7
• In a basic solution, adding water decreases the pH closer and closer to 7
• You can't reach a pH of 7 by simply diluting the solution with water and so you can't change an acid into a base or vice versa.

Practice Problems

5) because it was diluted so the pH decreased

7) a) .075 mol b) .068 M c) pH 1.17
