Question

What is the meaning of these lines: Hydrated halides of Be and Mg on heating suffer hydrolysis

Answer 1

Answer:

Explanation:

Hydrated halides of Be,Mg(Mgcl2.8H2O) on heating again lose water molecule to form Mgcl2 but due to high amount of hydration enthalpies of alkaline earth metal ions and alkali metal ions.These compounds of alkaline earth metals are more extensively hydrated due to the presence of moisture in atmosphere and form hydrates of Mgcl2 and Cacl2 which exist as Mgcl2.6H2O and Cacl2.6H2O and this is how metal suffers hydrolysis...

Answer 2

Answer:

Hydrated halides of Be and Mg on heating suffer hydrolysis.

The meaning of the above-given sentence is as follows:

Explanation:

Be - Beryllium

Mg - Magnesium

• These metals are alkaline earth metals.
• When heated the size of these metal atoms has an important role in the formation of products.
• The tendency to create halide hydrates is inversely proportional to the size of the metal atom.
• In other words, as we proceed down the group, the possibility of forming alkaline earth halide hydrates reduces.
• Thus, when heated it results in the dehydration of those halides with bigger cations (Ca, Sr and Ba). The ones with smaller cations (Be and Mg) has more tendency to form the halide hydrates.
• Hence, hydrated halides of Be and Mg on heating suffer hydrolysis.
