solubility of salts, oxides and hydroxides

list all the types of soluble salts

SNAP

• all group 1 metal salts

  • sodium, potassium, etc

• all ammonium salts

• all nitrates

state the solubility of chlorides

mostly soluble, all chlorides except:

• silver chloride

• lead(II) chloride

state the solubility of sulfates

mostly soluble, all sulfates except:

• barium sulfate

• lead(II) sulfate

• silver sulfate

• calcium sulfate (sparingly soluble)

state the solubility of carbonates

soluble:

• all group 1 carbonates

• ammonium carbonates (SPA)

insoluble:

• all other carbonates

state the solubility of metal oxides

basic oxide

• mostly insoluble except group 1

• group 2 increases solubility down the group

  • Mg insoluble

  • Ca sparingly soluble

  • Sr, Ba soluble

amphoteric oxide

• ZAP (zinc, aluminium lead) —> insoluble

state the solubility of non-metal oxides

acidic oxide —> soluble

neutral oxides —> neither basic nor acidic properties, do not react with water

• ie. H2O, CO, NO, N2O

state the solubility of halides

soluble:

• Cl- (Chloride) halides

  Br- (Bromide) halides

  I- (iodide) halides

insoluble:

• Ag+ (Sliver) halides

  Pb2+ (Lead II) halides

state the solubility of metal hydroxides

soluble: group 1, ammonium (alkalis)

sparingly soluble: calcium and barium

insoluble: rest of the hydroxides
