4.6 understand the general rules for predicting the solubility of salts in water


i) all common sodium, potassium and ammonium salts are soluble

ii) all nitrates are soluble

iii) common chlorides are soluble, except silver chloride

iv) common sulfates are soluble, except those of barium and calcium

v) common carbonates are insoluble, except those of sodium, potassium and ammonium

  1. except silver choride AND lead (ii) chloride
    and for sulphates lead (ii) is also not soluble

  2. What does it mean if it is soluble or insoluble?
    Solid? Aqueous?

    1. Soluble is to be able to be dissolved, especially in water, whereas insoluble is the exact opposite.
