Asked by Matt
You have three solutions, A, B, and C, each of which are believed to be one of the following: calcium hydroxide, potassium sulfate, and sodium chloride. Combining B and C results in the formation of a precipitate, but neither solution forms a precipitate with A. Also, adding iron (II) nitrate to each of the solutions only produces a precipitate with C.

You need to know solubilities for this.
B+C = ppt which means B or C must be Ca(OH)2 or K2SO4 (The ppt is CaSO4)
This means A definitely is NaCl.
Adding Fe produces a ppt with C so C mut be Ca(OH)2 (Fe(OH)2 is the ppt) and means B must be K2SO4.
