Give the formula of the compound which will give a precipitate with BaCl2 but NOT with (NH4) 2CO3?
SOLUBILITY RULES
Solubilities of ionic substances in water:
1) All salts of Na+, K+, NH4+ are soluble in water.
2) All salts of NO3-, CH3COO- are soluble in water.
3) All salts of Cl-, Br-, I- are soluble in water (except Ag+, Pb2+, Hg22+ )
4) All salts of SO42- are soluble in water ( except Ba2+, Pb2+, Sr2+)
SO42- of Ca2+, Ag+, Hg22+ are slightly soluble in water.
5) All salts of CO32-, PO43- are insoluble in water (except Na+, K+, NH4+)
6) All salts of S2- are insoluble in water ( except Na+, K+, NH4+, Ba2+,Ca2+, Mg2+, Sr2+)
7) All salts of O2-, OH- are insoluble in water ( except Na+, K+, NH4+, (Ba2+))
OH- of Ca2+, Sr2+, (Ba2+) are slightly soluble in water
OH- of Mg2+ is very very slightly soluble in water
