2. Vocabulary AcidBasepH pH scale Neutralization

3. Chemistry Matter will either be an acid, a base, or neutral Acid – A solution that has an excess of H+ ions Acids have a sour taste They can also corrode or react with metals

4. Chemistry

5. Chemistry Base – a solution that has an excess of OH- ions Bases have a slippery or slimy feel Bases have a bitter taste Bases are corrosive to skin Solutions that are neither an acid or a base is considered neutral
