Answer 2

Explanation:

Wool has the following chemical properties.

(1) Action of heat: It starts changing colour at 100 °C, but does not catch fire easily. It also becomes yellowish when left in a hot, humid atmosphere for a long time. So, the wool on the body of a sheep living in a hot, humid region may be yellowish.

(ii) Action of acids and bases: It dissolves in acids and alkalis.

(iii) Action of bleaching agents: The fibre can be bleached without loss of strength.
