Question

Predict which of the following compounds are soluble in water. (Select all that apply.)

-aluminum nitrate, Al(NO3)3>aluminum nitrate, Al(NO_3)_3>aluminum nitrate, Al(NO_3)_3

-lead(II) sulfate, PbSO4>lead(II) sulfate, PbSO_4>lead(II) sulfate, PbSO_4

-ammonium sulfide, (NH4)2S>ammonium sulfide, (NH_4)_2S>ammonium sulfide, (NH_4)_2S

-iron(III) phosphate, FePO4>iron(III) phosphate, FePO_4>iron(III) phosphate, FePO_4

Chem Man · Accepted Answer

Al(NO3)3 - soluble (all nitrates are soluble).
PbSO4 - insoluble.
(NH4)2S - soluble (all ammonium compounds are soluble).
FePO4 - insoluble
