Auto-protolysis (self-ionization) of water is a chemical reaction in which 2 water molecules react to produce a hydroxide ion (OH–) and a hydronium ion (H3O+).
The reaction involved can be represented as:
\( H_{2}O_{(l)}+H_{2}O_{(l)}\leftrightarrow H_{3}O^{+}_{(aq)}+OH^{-}_{(aq)} \)
Auto- protolysis of water indicates its amphoteric nature i.e., its ablity to act as an acid as well as a base.
The acid- base reaction can be written as :
\( H_{2}O_{(l)}+H_{2}O_{(l)}\leftrightarrow H_{3}O^{+}_{(aq)}+OH^{-}_{(aq)}\)
Answered by Pragya Singh | 1 year agoWhat 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?
