could someone help with this question
Which of the following solutions will form a precipitate when added to a solution of potassium sulfate?
A. Magnesium chloride solution B. Sodium carbonate solution
C. Lead nitrate D. Copper (II) bromide solution

Thanks

Adding Pb(NO3)2 to K2SO4 will trigger a double-displacement reaction that produces PbSO4(s), which is an important exception to the "sulfates are soluble" rule. "Precipitation" implies the formation of a solid product.
