Question

Which alkaline earth metal is the component of the ff materials a,lime ston b,slaked lime c, quick lime d, gypsum e, epsom salt

Answer 1

Answer:

The sulphates of alkaline earth metals are all white solids. Solubility:The solubility of the sulphates in water decreases down the groups i.e. Be > Mg > Ca > Sr > Ba. Thus BeSO4 and MgSO4 are highly soluble, CaSO4 is sparingly soluble but the sulphates of Sr, Ba and Ra are virtually insoluble.

Answer 2

Answer:

a) limestone - Calcium

b) slaked lime - Calcium

c) quick lime - Calcium

d) gypsum - Calcium

e) Epsom salt - Magnesium 

Explanation: The following is the chemical formula of the given compounds.

• CaCO3 - Limestone

• Slaked lime - Ca(OH)₂

• Quicklime - CaO  

• Gypsum - CaSO4⋅ 2H2O  

• Epsom salt - MgSO₄

Here calcium is the alkaline rare earth metal in limestone, slaked lime, quicklime, gypsum, and in Epsom salt its Magnesium.
