Caco3

Calculate molarity of CaCO_(3) (aq.) solution which has concentration of CaCO_(3)=200 ppm.

Hardness of a water sample is 100 "ppm" CaCo_(3) . Thus molarity of CaCO_(3) is

"2.6 g of CaCO"_(3) and MgCO_(3) mixture is heated to a constant weight of 1.3 g. The mass of CaCO_(3) in mixture is :

BaCO_3,CaCO_3,SrCO_3,MgCO_3 arrange these salts according to their decreasing thermal stability?

Calculate the solubility at 25^(@)C of CaCO_(3) in a closed container containing a solution of pH 8.60. [K_(sp)(CaCO_(3)) = 10^(-8)]

100g CaCO_(3) is taken in a closed container (15 lit ) ,heated at "1000k" and equilibrium attained according to reaction CaCO_(3) (s) harr CaO(s)+ CO_(2) (g) .If "75%" of CaCO_(3) was decomposed at equilibrium. The value of k_(p) is-

Calcualte the number of oxygen atoms and its weight in 50 gm of CaCO_(3)
