How can we know if the salt of a metal or non metal is soluble in water or not?(e.g: is silver nitrate soluble in water, is sodium acetate is soluble in water, is magnesium oxide soluble in..........)

Expert Answer:

  • nitrates, chlorates, and acetates of all metals are soluble in water. Silver acetate is sparingly soluble.
  • All sodium, potassium, and ammonium salts are soluble in water.
  • chlorides, bromides, and iodides of all metals except lead, silver, and mercury(I) are soluble in water. HgI2 is insoluble in water. PbCl2, PbBr2, and PbI2 are soluble in hot water. The water-insoluble chlorides, bromides, and iodides are also insoluble in dilute acids.
  • sulfates of all metals except lead, mercury (I), barium, and calcium are soluble in water
  • carbonates, phosphates, borates, sulfites, chromates, and arsenates of all metals except sodium, potassium, and ammonium are insoluble in water but soluble in dilute acids. MgCrO4 is soluble in water; MgSO3 is slightly soluble in water.
  • sulfides of all metals except barium, calcium, magnesium, sodium, potassium, and ammonium are insoluble in water. BaS, CaS, and MgS are sparingly soluble
  • hydroxides of sodium, potassium, and ammonium are very soluble in water. The hydroxides of calcium and barium are moderately soluble.
