    Physical and chemical properties of acids:

    Acids are sour in taste.

    All acids have pH less than 7.

    All acids turns blue litmus paper red.

    Acids react with metals and form salts.

    HCl + Mg → MgCl₂ + H₂

    Acids react with base and form salt and water.

    HCl + NaOH → NaCl + H₂O

    Acids react with carbonates and form carbon dioxide, water and salt.

    2HCl + CaCO₃ → CaCl₂ + H₂O + CO₂

    Physical properties of bases:

    All bases are bitter in taste.

    They turn litmus paper from red to blue.

    They are slippery.

    All bases have pH above 7.

    Bases react with acid and form water and salt.

    NaOH + HCl → NaCl + H₂O

    Bases conduct electricity.

    Bases such alkali when react with water produces OH⁻.
