Predict whether the compounds are soluble or insoluble in water. Soluble Insoluble Answer Bank Znco; PbCl2 Pb(NO3)2 cucl, BaSO4 K2SO4
A precipitation reaction occurs when a solution containing a cation (red spheres) and a solution containing an anion (green spheres) are mixed. The spectator ions have been omitted from the diagram for clarity. Which set of reactants best represents the diagram? NaClo, (aq) + CaCl,(aq) O KNO3(aq) + CuCl(aq) O Li,SO4 (aq) + AgNO3(aq) O NH Br(aq) + Pb(C,H,O2)2 (aq) Write the net ionic equation for the reaction. Include physical states. net ionic equation: || 2Ag(aq) + SO (aq) — Ag, SO,(s)
Answer
Insoluble exceptions Soluble compounds | 1. Compound containing alkali metals and NH4ion 2. Nitrates (NO3-), bicarbonates (HCO3-) chlorates (C10,-) and perchlorates (C10,-) 3. Hali des(C1-, Br” and I”) 4. Sulfates (S0,2-) Halides of Ag+, Hg2+ and Pb2+ Sulfates of Ag+, Ca2+, Sr2+, Ba2+, Hg2+ and Pb2+ Insoluble compounds 1 Carbonatesico 2-1 Phsphates(PO.3-1 Chromates ( Cr0,2-) and sulfi des (52) 2. Hydroxides (OH) Soluble exceptions Compounds containing alkali metal ions and NH,* ion Compounds containing alkali metal ions and Ba2+ ion
Thus, among the given compounds, soluble compounds are; Pb(NO3),, CuCl2, K2SO4 Insoluble compounds are; ZnCO3, PbCl2, BaSO4
