why are some barium and calcium salts insoluble while some are soluble??

Sodium salts often is the customerrsquo;s preferred salts because of the comparatively lower price. Potassium salts work the same way sodium salts. Because extracting potassium salts is more costly than...

Yes. The reaction is: Ba(OH)2 + 2CH3COOH -> 2H2O + Ba(CH3COO)2

All are soluble in water. It means that a compound dissolves in water, saying in other words, they form one phase upon mixing with water. They are soluble because all...

can potassium carbonate remove calcium hardness from water instead of Sodium Carbonate,I have a KCl solution 20g/l with Calcium 500mg/l, I would normally use Na2CO3 to remove the calciumSolution:yes you...

Because alcohols form hydrogen bonds with water, they tend to be relatively soluble in water. The hydroxyl group is referred to as a hydrophilic (“water-loving”) group, because it forms hydrogen...

Solution:The balanced chemical equation:3Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2OAccording to the equation above: Moles of Ca(OH)2 / 3 = Moles of H2O / 6Moles of Ca(OH)2 = Moles of...

CaCO3 = CaO + CO2 nCO2 = nCaCO3 = mCaCO3/MWCaCO3 = 10.5 g/100.0869 g/mol = 0.1049 mol; VCO2 = nCO2*Vm = 0.1049 mol*24 L/mol = 2.5178 L ≈ 2.52 L

Ca(OH)2 + 2HNO3 = 2H2O + Ca(NO3)2 0.0900 mol HNO3 x (1 mol HNO3 / 1 mol Ca(OH)2) = 0.0900 mol Ca(OH)2

Ca(OH)2 + 2HCl —> CaCl2 + 2H2O0.15N (HCl) = 0.015kg = 15gNo of moles of HCl = 15/(2*35.5) = 15/71 = 0.211mol/dm3With HCl as the limiting reagentand molar mass of...
