Q: In thiosulphuric acid:

In thiosulphuric acid there is a S=S linkage present.One S atom is in -2 and other sulphur atom is in +6 oxidation state.There are two replaceable hydrogen atom.Option B is correct.

Q: Which oxoacid of sulphur contain S - S bond in its structure?

Di sulphurous acid (H_2S_2O_5) contain S-S bond in its structure.So answer is A.

Question 1

The oxidation state of  S  in  Na_2S_4O_6  is:

Accepted Answer

O.N of  S  is  X O.N of  Na  is  +1 O.N of  O  is -2Sum of all O.N is  2	imes +1+(4X)+(6)	imes -(2) 4X-10  is equal to 0 X  equals to 10/4 which equals to 2.5his compound must have sulfur atoms with mixed oxidation states. Since it is normal for sulfur to have oxidation states of -2, 0, +2, +4, and +6,  it is most likely that there are three sulfurs with a +2 oxidation state and one sulfur that is +4.Hence option  A  is correct.

Question 2

Which of the following are peroxoacids of sulphur?

Accepted Answer

Peroxy linkage means in a compound there should be bond between oxygen and oxygen ( O-O )In the above oxoacids of sulfur only  H_2SO_5,H_2S_2O_8  ha spoeroxy linkage.Hence option A is correct.

Question 3

There is no S-S bond in:

Accepted Answer

There is no S-S bond in  S_2{O}^{-2}_{7} .

Question 4

The oxidation states of  S  atom in  S_4O_6^{2-}  from left to right respectively are

Accepted Answer

The two middle sulphur in structure have 0 oxidation state because any atom bonded with similar atoms has an oxidation state of 0.  The total oxidation state of sulphur in the compound is 10. The oxidation state of leftmost and rightmost sulphur is +5, as oxygen is more electronegative.

Question 5

Write the name and structure of any five oxyacids of sulphur?

Accepted Answer

Oxyacids of sulphur are as shown in the diagram.(i) Sulphurus acid  H_2SO_3 (ii) Sulphuric acid  H_2SO_4 (iii) Thiosulphuric acid  H_2S_2O_3 (iv) Pyrosulphuric acid  H_2S_2O_7 (v) Peroxymono sulphuric acid  H_2SO_3

Question 6

Identify the correct sequence of increasing number of  \pi  - bonds in the structures of the following molecules :I)  H_{2}S_{2}O_{6}  II)  H_{2}SO_{3} III)  H_{2}S_{2}O_{5}

Accepted Answer

H_{2}S_{2}O_{6} \pi - bonds = 4 H_{2}SO_{3} \pi - bonds = 1 H_{2}S_{2}O_{5} \pi - bonds = 3 II  <  III  < I

Question 7

Hydrolysis of one mole of peroxodisulphuric produces :

Accepted Answer

Hydrolysis of one mole of peroxodisulphuric acid produces one mole of sulphuric acid and one mole of peroxomonosulphuric acid. H_2S_2O_8 + H_2O \longrightarrow H_2SO_4 + H_2SO_5   Option (C) is correct.

Question 8

Which of the following oxoacid of sulphur has  - O - O -  linkage?

Accepted Answer

OH-\overset{O}{\overset{||}{\underset{O}{\underset{||}{S}}}}-OH H_2SO_4 OH-\overset{O}{\overset{||}{\underset{O}{\underset{||}{S}}}}-O- O-\overset{O}{\overset{||}{\underset{O}{\underset{||}{S}}}}-OH H_2S_2O_8 HO-\overset{O}{\overset{||}{\underset{O}{\underset{||}{S}}}} -O-\overset{O}{\overset{||}{\underset{O}{\underset{||}{S}}}}-OH H_2S_2O_7 OH-\overset{O}{\overset{||}{S}}-OH H_2SO_3 As the structure shown  H_2S_2O_8  contains  -O-O-  linkage.Option B is correct.

Question 9

In thiosulphuric acid:

Accepted Answer

In thiosulphuric acid there is a  S=S  linkage present.One S atom is in -2 and other sulphur atom is in +6 oxidation state.There are two replaceable hydrogen atom.Option B is correct.

Question 10

Which oxoacid of sulphur contain S - S bond in its structure?

Accepted Answer

Di sulphurous acid (H_2S_2O_5)  contain S-S bond in its structure.So answer is A.
