Question

Match column I with column II and mark appropriate choice.

Thiosulphuric acid	(i) ${H_2}S{O_5}$
Caro’s acid	(ii) ${H_2}{S_2}{O_6}$
Marshall’s acid	(iii).${H_2}{S_2}{O_3}$
Dithionic acid	(iv).${H_2}{S_2}{O_8}$

A.$(A) \to (i);(B) \to (ii);(C) \to (iii);(D) \to (iv)$
B.$(A) \to (iv);(B) \to (iii);(C) \to (ii);(D) \to (i)$
C.$(A) \to (iii);(B) \to (i);(C) \to (iv);(D) \to (ii)$
D.$(A) \to (ii);(B) \to (iii);(C) \to (i);(D) \to (iv)$

Answer 1

Hint: We have to know that the acid is a substance that gives protons or acknowledges a couple of valence electrons to shape a bond. A base is a substance that can acknowledge protons or give a couple of valence electrons to shape a bond. Bases can be considered as the compound inverse of acids.

Complete answer:
We have to know that, Thiosulphuric acid is also called sulfur oxoacid. The acid cannot be made by acidifying watery thiosulfate salt arrangements as the corrosive promptly decays in water. Therefore, the formula of Thiosulphuric acid is ${H_2}{S_2}{O_3}$ .
Therefore, $(A) \to (iii)$ .
We have to know that the Caro's acid, sometimes called Peroxymonosulfuric acid, per-oxy sulfuric acid, is persulfuric corrosive. The formula of Caro's acid is ${H_2}S{O_5}$ .
Therefore, $(B) \to (i)$ .
We have to know that Marshall's acid is an inorganic compound with a substance equation ${H_2}{S_2}{O_8}$ . It is additionally called Peroxydisulfuric acid. The acid is set up by the response of chloro-sulfuric acid with hydrogen peroxide.
Therefore, $(C) \to (iv)$ .
We have to know that, Di-thionic acid is diprotic and salts called di-thionates are known. No corrosive salts have been found. All di-thionates are promptly dissolvable in water. They are gentle oxidizing and gentle lessening specialists. The formula of Di-thonic acid is ${H_2}{S_2}{O_6}$ .
Therefore, $(D) \to (ii)$ .

Hence, option C is correct. $(A) \to (iii);(B) \to (i);(C) \to (iv);(D) \to (ii)$ .
The correct table of column I and column II,

Thiosulphuric acid	${H_2}{S_2}{O_3}$	(iii)
Caro’s acid	${H_2}S{O_5}$	(i)
Marshall’s acid	${H_2}{S_2}{O_8}$	(iv)
Dithionic acid	${H_2}{S_2}{O_6}$	(ii)

Note:
We have to know, the properties of acids, acids are destructive in nature. They are acceptable conduits of power. Their $pH$ esteems are in every case under seven. When responded with metals, these substances produce hydrogen gas. Acids are acrid tasting substances.
