pH scale Measures the amount of H + in a solution. Scale used to measure whether a substance is an acid or a base. Lower numbers are acids. Higher numbers.
Aim: How to identify acids and bases by using the pH scale? An electrolyte is a substance which, when dissolved in water, forms a solution capable of conducting.

Today: pH Lab What’s pH? Measure of acidity

https://www.youtube.com/watch?v=K o5iDMYzwWE pH? Magic? https://www.youtube.com/watch?v=K o5iDMYzwWE Brief discussion

pH pH is how we measure acidity pH scale is 0 to 14 0 is very acidic, 7 is neutral, 14 is very basic Acidity has to do with how many hydrogen ions (H+) a solution has (more H+ = more acidic) Another word for basic is alkaline or alkali

Today: Testing Household Substances Read through protocol
