Tincture of iodine is a mixture of two materials X and Y. The material Y has a property that its solid form can be converted directly into vapours on heating by a process called Z.(a) What could X be ?(b) What could Y be ?(c) Name the process Z.(d) Which process would you use to recover both the components X and Y from tincture of iodine ?(e) Which process can be used to recover only components Y from tincture of iodine?
(a) Tincture iodine is a mixture of two materials X and Y. Hence, X is alcohol.
(b) The material Y has a property and its solid form can be converted directly into vapours on heating by the process called Z. Hence, Y is iodine.
(c) Process Z is called sublimation.
(d) The process used to recover both the components, i.e., alcohol and iodine, from the tincture of iodine is distillation.
(e) The process used to recover component Y only from the tincture of iodine is evaporation.
