Explain the terms: "oxidising agent" And "reducing agent". Select from the following substances examples of each, and write an account of the ው እ -- periments you would perform with them to illustrati your answer: hydrogen, carbon monoxide, chlorine, sulphur dioxide, nitric acid, potassium permangan-. ate.
Answer.
A substance is said to be oxidised when
(1) it adds on oxygen, chlorine, sulphur or other
atoms
or groups capable of forming electro- negative radicals or anions
(2) it loses hydrogen, metal, or electropositive)
radicals or cations,
(3) it loses electrons,
A substance is said to be reduced when
(1) it loses oxygeny chlorine, sulphur, or other
atoms or groups capable of forming electro- negative radicals or anions,
(2lit gains hydrogen, metal_or_elecvropositive/
radicals or cations,
(3) it gains electrons.
Therefore an oxidising agent is one which is capable of causing substances to be oxidised and is then able to impact to them oxygen, chlorine, sulphur, electronegative radicals, etc.for to remove hydro- gen, metal or electrons from them. Similarly, a reducing agent is one which is capable or causing substances to be reduced by removing from them oxygen, chlorine, sulphur, electronegative radi- cals, etc., or by imparting hydrogen, metal or elec- trons.to. them.
First example of an oxidising agent chlorine.
Chlorine oxidises by adding oxygen to other subs- tances. Thus if to a solution of sodium sulphite chlorine gas is passed, the sulphite is converted to a sulphate, which can be identified by the form- ation of a white precipitate insoluble in dilute hydrochloric acid when barium chloride is added..

ji Na2SO.g + H2O + Cl2 = Na2504 Oxidation is carried out by imparting chlorine toʻ another, substance. Thus to a solution of ferrous chloride chlorine gas is passed, The iron is changed from the ferrous to the ferric state, which can be proved by the formation of a reddish-brown preci-. pitate when sodium hydroxide is added.

Question 18.
(*) 4.5. g. of a metal M produce 5.3 gm of the oxide
of the metal. Calculate the equivalent of M.
(b) What volume of hydrogen (at N.T.P.) would you
expect 7.5 gm of the metal to displace from an cess of a diluts neid?
(a) What would be the volume of this hydrogen at
17°c. and 740mm、pressure?,
(d) Define atomic weightr
OXF
(e) How is the atomic weighs related to the equiva
lent weight of an element?
(f) Assuming the valency of M to be 2, calculate the
atomic weight of the metal.
(g) Write the formulae for the bromide, sulphide,
hydroxide. nitrate, and sulphate of M.
Anewer.
(a) The equivalent weight of a metal is the number of grams of the metal that will combine with 8 強 of oxygen.
6.3 - 4.5 = 1.0 gm of oxygen combine with 4.3 gm
of the metal M.
Therefore 8 gm of oxygen combine with 4e218
1.8 =.20 gm of M.
The equivalent of the metal M is 20, (b) The equivalent of a metal is the number of grana
of the metal that will displace 1 gm of hydro- gen, 1.0., at N.T.P. 11,200 ml. of hydrogen.
The gram-molecular volume of any gas is the vol. ume occupied at N.T.P. by one molecular weight.
of any gas, which is equal to 22.4 litres.) 20 gm of M will displace 11,200 ml of hydrogen at N.T.P.
Therefore 7.5 gm of M will dispiace
11:200 * 7.5
= 560 x 7.5 - 4,200 ml. 20 7,5 gm of M`will displace 4,200 ml hydrogen
at N.T.P. (c). 4,200 ml of a gas at N.T.P. are at 17 ́0 and

760 740
m1 = 4381 ml
The volume of hydrogen at 17°C and 740 mm would
be 4581 ml
(d) The atomic weight of an element is the ratio of
the weight of one atom of the element to one- sixteenth of the weight of one atom of oxygen. Examplest hydrogen 1.008; oxygen 16; chlorine.
35.5.
(e) The ratio of the atomic weight of an element to the equivalent weight of the same element is always a whole number. The number is called the valency of the element. In different series of compounds an element may have different equi- valent weights and different valencies, but the product of equivalent weight and valency is for all series the game, viz, the atomic weight of the element.
! Example: the equivalent weight of carbon is 3, the valency 4, the atomic weight = 3 x 4 = 12. (f) For the metal M the equivalent weight. was found ta be. 20。 The valency is 2. The atomic weight is therefore 20
