1. Mixing solutions of sodium bromide with magnesium nitrate
Net ionic equation: Na+(aq) + Br(aq) + Mg+2(aq) + NO3-(aq) no rxn
Precipitate: N/A
This looks ok.
2. Mixing solutions of barium acetate with sodium phosphate
Net ionic equation: Ba+2(aq) + CH3COO-(aq) + Na+(aq) + PO4-3(aq) no rxn
Isn't Ba3(PO4)2 insoluble?
3. Mixing solutions of thallium sulphate with magnesium chloride
Net ionic equation: Te+(aq) + SO32-(aq) + Mg2+(aq) + Cl-(aq) Te+(aq) + Cl-(aq) + MgSO3 (s)
Precipitate: Yes
Thallium isn't Te. sulfate isn't SO4^-2. Yes is correct but the question asks you to name the ppt.
4. Mixing solutions of strontium chloride with copper sulphate
Net ionic equation: Sr2+(aq) + Cl-(aq) + Cu+(aq) + SO3-2(aq) Cl-(aq) + Cu+(aq) + SrSO3(s)
Precipitate: Yes
copper sulphate is CuSO4. The ppt is SrSO4 and it is white.
5. Mixing solutions of copper acetate with potassium chloride
Net ionic equation: Cu+(aq) + CH3COO-(aq) + K+(aq) + Cl-(aq) no rxn
Precipitate: N/A
copper(II) acetate is Cu(CH3COO)2.
For each of the following, write a net ionic equation (modeled above). Wherever there is a precipitate, state the name of the precipitate (e.g “lead iodide” from above). Pop onto the net and see if you can find a description of the physical properties (e.g colour) of this precipitate.
