This water is free from all the soluble mineral salts and it doesn’t contain any cation or anion. It is obtained successively by passing the water through anion exchange and cation exchange resin.
During the cation exchange process, H+ exchanges for and other cations present in the water.
→ Ca2+
→ Na+
→ Mg2+

What do you understand by the terms :
(i) Hydrogen economy
(ii) Hydrogenation
(iii) ‘syngas’
(iv) Water-gas shift reaction
(v) Fuel cell?
Do you expect different products in solution when aluminium (III) chloride and potassium chloride treated separately with
(i) alkaline water
(ii) acidified water, and
(iii) normal water. Write equations wherever necessary.
What do you expect the nature of hydrides is, if formed by elements of atomic numbers 15, 19, 23 and 44 with dihydrogen? Compare their behaviour with water.
How can saline hydrides remove traces of water from organic compounds?
