is soluble in water whereas fluorides of other alkaline earth metals are insoluble because of
is soluble in water whereas fluorides of other alkaline earth metals are insoluble because of
being small in size is heavily hydrated and heat of hydration exceeds the lattice energy. Hence 
is soluble in water.Which category of salts of alkaline earth metals is not found in solid sate, but found in solution state?
Among the given statements, the incorrect one is

Amongst the following hydroxides, the one which has the lowest value of 
is :
is insoluble in water and thus has lower value of 
reacts with water forming propyne gas. 
ions has:

Two metals 
and 
belong to the same group of the periodic table. Metal (A) forms an insoluble oxide but a soluble sulphate, metal (B) forms a soluble oxide but an insoluble sulphate. Both metals (A) and (B) form hydroxides which are soluble in alkalis. (A) and (B) are
is insoluble, whereas 
is soluble, whereas 
is soluble, but 
is insoluble.Calcium imide on hydrolysis gives gas (B) which on oxidation by bleaching powder gives gas 
. Gas (C) on reaction with magnesium give compound (D) which on hydrolysis gives again gas (B). Identify (B), (C) and (D).
Which one is the correct statement with reference to solubility of 
in water?
is the only alkaline earth metal sulphate which is soluble in water and for solubility hydration energy should be greater than lattice energy.A solid compound ' 
' on heating gives 
gas and a residue. The residue mixed with water forms 'Y'. On passing an excess of 
through ' 
' in water, a clear solution 'Z' , is obtained. On boiling 'Z', compound 'X' is reformed. The compound 
is

, where as plaster of paris is 
or 
Which of the following alkaline earth metal sulphates is the most soluble in water?
What are the products formed when an aqueous solution of magnesium bicarbonate is boiled?
