• 1.0 x 10-7  M

What does a pH scale do?

• Tells you if a substance is an acid.
• Tells you if a substance is a base.
• Measures the strength or weakness of an acid or base.
• All of these are true.

Which is the stronger acid?

• pH 1
• pH 4
• pH 8
• pH 13

Acid + Base ₋--> 

• salt + hydrogen
• salt + water
• salt + carbon dioxide + water
• salt

The pH of a solution is tested, and it is found to be a basic solution. Of the following choices, what could the pH have been?

• 9
• 7
• 5

What is the approximate pH of seawater?

• 2
• 5
• 7
• 9

Which food is the most acidic?

The pH scale measures...

• ...the strength of an acid.
• ...the strength of hydrogen ions.
• ...the concentration of hydrogen ions.
• ...the concentration of an acid

HSO₄^-(aq)+H₂O(l) → H₃O⁺(aq)+SO₄^2-(aq)
