Name the two possible products in the precipitation reaction of copper
When solutions of copper(II) chloride and sodium phosphate are allowed to react they give a solid precipitate of copper(II) phosphate and an aqueous solution of sodium chloride. The empirical formula is the simple whole-number ratio of atoms of the different elements present in the molecule of the compound.

Which salts can be used to precipitate chloride ions? [closed]
Mercury(I) chloride is similarly badly soluble, but toxic (and unstable, disproportionation) and therefore bad practice. Lead(II) chloride is already far more soluble (4 g/l) than AgCl, and practically all other simple chlorides are just very well soluble in water. Silver nitrate is cheap, the internet sells 10 g high purity $ce{AgNO3}$ for 25 ...

Problem Droping the Platinum out of Aqua Regia
You'll find it precipitates much better, and possibly completely. Use an excess of ammonium chloride----it does no harm. My practice was to use about 25% more than necessary, which I dissolved in hot water. As you likely know, the water turns cold upon dissolution of the ammonium chloride----so don't start with cold water. Takes too long to ...
