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.

Solution

Tincture of iodine is prepared by dissolving proper amount of iodine in an alcohol solution.

(a) So X could be alcohol.

(b) So Y could be iodine.

(c) When the solid phase directly converts to gas phase on heating, it is known as sublimation. So, process Z is sublimation.

Q. A strip of metal X is dipped in a blue coloured salt solution YSO₄. After some time, a layer of metal Y from the salt solution is formed on the surface of metal strip X. Metal X is used in galvanisation whereas metal Y is used in making electric wires. Metal X and metal Y together form an alloy Z.

There are three substances X, Y and Z. The substance X does not have a fixed melting point or boiling point and it still shows the individual properties of its constituents. The substance Y is a pure substance which occurs in nature as such. The substance Y has a fixed melting point and boiling point but it cannot be broken down into simpler substances by any chemical means. The substance Z is also a pure substance whose properties are entirely different from those of its constituents. The substance Z can, however, be divided by electrolysis into two substances which belong to the same class of substances as Y.

(a) What type of substance could X be? Name one substance like X.

(b) What type of substance could Y be? Name one substance like Y.

(d) Which process involves absorption or release of an appreciable amount of energy: formation of substances X or formation of substance Z?

(e) Name the three groups into which all the substances like Y are divided on the basis of their properties.
