Precipitation Reactions Help Please??
Q. Can someone please help me with these three chemical reactions? I have to answer ten and I at least need to understand the first three before I can do everything else on my own. Please help! What's the product, precipitate, spectator ions and net ionic equation? 1) K2CrO4 + Pb(NO3)2 --> ? 2) Hg2(NO3)2 + K2SO4 --> 3) FeCl3 + NaOH --> --- Thanks! =P

Chemistry Solubility Question?
Q. Using the solubility rules, which one of the following compounds will not be soluble in water? A. MgCl2 B. K2SO4 C. AgCl D. NaOH E. LiNO3
Asked by Troy Mabry - Tue Nov 17 20:25:30 2009 - - 2 Answers - 0 Comments
A. solubility rules: 1. nitrates=always soluble 2. alkali metals and ammonium salts are always soluble 3. sulfates are soluble except in Ag, Ba, Pb, Hg, and Ca 4. halides are soluble except with Ag, Pb, and Hg 5. Hydroxides are almost insoluble except with Al, ammonium, and alkali metals. 6. phosphates, carbonates, sulfides, and chromates are all insoluble except with alkali metals and ammonium. therefore a is soluble B is soluble C is insoluble d is soluble E is soluble.
