How can you measure the pH of a solution?
Indicator
Using a pH probe attached to a pH meter
Acid
A substance that forms an aqueous solution with pH <7
Form H+ ions in water
Base
Any substance that will react with an acid to form a salt
Alkali
A base that dissolves in water to form a solution with pH >7
Form OH- ions in water
Equation when an acid reacts with a base?
Acid + Base —> Salt + Water
Equation when an acid reacts with a metal oxide
Acid + Metal Oxide —> Salt + Water
Equation when an acid reacts with a carbonate
Acid + Carbonate —> Salt + Water + Carbon Dioxide
