(i) Rusting is a double decomposition reaction.
(ii) Silver salt are generally sensitive to light.
Which of these statement(s) is/are correct?
(a) (i) only (b) (ii) only
(c) Both (i) and (ii) (d) Neither (i) nor (ii)
Answers
Answer is (b) 2nd only
Answer:
The correct answer to the question-"Consider the following statements:
(i) Rusting is a double decomposition reaction.
(ii) Silver salt are generally sensitive to light." is-
(b) (ii) only
Explanation:
(i) The statement -"Rusting is a double decomposition reaction " is-
It is incorrect. It is not a double decomposition reaction .Since, the corrosion of iron is known as rusting. Thus, it is an oxidation reaction as the oxidation of Fe results in the increase from 0 to +3.
(ii)The statement-" Silver salt are generally sensitive to light." is-
It is correct. They are generally sensitive to light.
They are those chemical compound which are light-sensitive and thus, decomposes easily in a photolytic reaction.
It loses its characteristic and forms chlorine gas and silver when it reacts with light,. Thus, they are kept in dark-colored bottles.
Therefore, only statement (ii) ,that is-
(ii) Silver salt are generally sensitive to light.
is the correct statement.
