Acids, Bases and Salts

Properties of Acids
1. an acid forms hydrogen ions in an aqueous solution.
2. Turns blue litmus paper red
3. Acid + Metal -----> Salts + Hydrogen
4. Acid + Base -----> Salt + Water
5. Acid + Alkali -----> Salt + Oxide
6. Acid + Carbonate -----> Salt + Water + Carbon Dioxide
Properties of Alkalis
1. an alkali forms hydroxide ions in an aqueous solution.
2. Turns red litmus paper to blue.
Salts
1. Solubility rules
2. Preparation methods:
  1. Is the salt SOLUBLE?
    1. YES: Is it a soluble Carbonate? (Na, K, NH4)
      1. YES: Titration: ACID+ ALKALI
      2. NO: Is the metal UNREACTIVE? (K, Na and C or Cu, Ag and Au)
        YES: Dissolving and Filtering: ACID + BASE (or CARBONATE)
        NO: Dissolving and Filtering: ACID + METAL
    2. NO: Precipitation
