Cis soluble in water and in nitric acid HNO3. It does not give a precipitate with Ba(NO3)2 solution but gives a precipitate with AgNO3 solution and the precipitate is not soluble in any strong acid. When solid C is heated, white smoke is observed. C SOLUBILITY RULES Solubilities of ionic substances in water: 1) All salts of Na*, K*, NH4+ are soluble in water. 2) All salts of NO;, CH;CO0- (C2H302) are soluble in water. 3) All salts of Clr, Br, I are soluble in water (except Agt, Pb2-, Hg,2+) 4) All salts of SO,2- are soluble in water ( except Ba2+, Pb2-, Sr2+) so,2- of Ca2+, Ag*, Hg22- are slightly soluble in water. 5) All salts of CO;2, PO- are insoluble in water (except Na*, K*, NH4*) 6) All salts of S2- are insoluble in water ( except Na*, K*, NH, Ba2+ Ca2+, Mg2+, Sr2-) 7) All salts of 02-, OH- are insoluble in water ( except Na", K*, NH4*, (Ba2-)) OH of Ca2+, Sr2-, (Ba2+) are slightly soluble in water OH of Mg?- is very very slightly soluble water STRONG ACIDS STRONG BASES HCI LIOH…
