Reactions of acids

• Metal oxides and metal hydroxides are bases.
• Acid + metal oxide -> salt + water
• Acid + metal hydroxide -> salt + water
• Hydrochloric acid = 2HCl
• Sulfuric acid = H2SO4
• Nitric acid = HNO3
• Copper oxide = CuO
• Potassium hydroxide = 2KOH
• Sodium hydroxide = NaOH
• Copper chloride = CuCl2
• Potassium sulfate = K2SO4
• Sodium nitrate = NaNO3
• Acid + metal carbonate -> salt + water + carbon dioxide
• Acid + metal -> salt + hydrogen
• Metal + water -> metal hydroxide + hydrogen
