When the pH of a solution becomes more basic, the number on the pH scale

• decreases

• increases

• stays the same

• triples

• 1

• 7

• 10

In a water solution, how do acids differ from bases?

• Acids form salts, but bases do not

• Acids turn litmus blue, while bases turn litmus red

• Acids form hydrogen ions (H+), while bases form hydroxide ions (OH-)

• Bases form salts, but acids do not

When you mix an acid and a base, you get

• acid and metal

• acid and base

• base and water

• salt and water
