Acids
1.Taste sour
2. pH less than 7
3. Acids turn blue litmus to red
4. Acids turn methyl orange to red
5. Acids neutralize bases producing a salt
and water
6. Proton donors
(Proton = H+
= hydrogen ion)
Increase H+
7. ion concentration in solution
8. Acids are electrolytes
9. Acids react with carbonates to produce a
salt, water and CO2
10. Acids react with active metals to produce
hydrogen
Bases
1.Taste Bitter
2. pH greater than 7
3. Bases turn red litmus to blue
4. Bases turn methyl orange to yellow
5. Bases turn phenolphthalein to
purple
6.Bases neutralize acids producing a salt
and water
7.Proton acceptors
8. Increase OH-
ion concentration in solution
9.Bases are electrolytes
10. Bases feel slippery
1. React with litmus paper
2. Release ions in solution
3. Combine to form salt and water
4. Corrode materials
5.Burn skin
