Consider the following chemical equation : 2NaOH + H2SO4
Consider the following chemical equation :
2NaOH + H2SO4 \(\longrightarrow\) \(Na_2SO_4 + 2H_2O\)
The informations conveyed by this equation are :
I. NaOH reacts with H2SO4 to produce \(Na_2SO_4\) and water.
II. For every one molecule of H2SO4, two molecules of NaOH are required.
III. Acids and bases are non-ionic in nature.
IV. This is not a redox reaction.
(a) I and II, IV
(b) II and III
(c) III and IV
(d) I and IV

Correct answer is (a) I, II and IV
2 NaOH + H2SO4 \(\longrightarrow\) Na2SO4 + 2H2O
(i) According to given chemical equation, we can clearly see that NaOH reacts with H2SO4 to produce Na2SO4 and water
(ii) The given chemical equation is a balance equation. we can clearly see that, one molecule of H2SO4, reacts with 2 molecule of NaOH and produced one molecule of Na2SO4 and two molecule of water (H2O).
(iii) acids and bases are ionic in nature, in equations solution, they decomposed like that -
NaOH \(\overset{H_2O}{\longrightarrow}\) \(Na^{+}(aq) + \overset{\ominus}{OH}(aq)\)
\(H_2SO_4\, \overset{H_2O}{\longrightarrow}\,H_3O^+ +HSO_4{^-}{(aq)}\)
(iv) The given reaction is a example of double displacement reaction, also you can say that it is a neutralization reaction. There is no change in oxidation state of any atoms. that is why it is not a redox reaction.
