D
(1) $$\rightarrow$$ (iii), (2) $$\rightarrow$$ (iv), (3) $$\rightarrow$$ (i), (4) $$\rightarrow$$ (ii)

Solution

Bleaching Power $$\rightarrow$$ Decolourisation
Baking soda $$\rightarrow$$ Antacid
Washing Soda $$\rightarrow$$ Preparation of glass
Sodium chloride $$\rightarrow$$ Production of $$H_2$$ and $$Cl_2$$
Question 2
1 / -0

The sodium compound which is used for softening hard water:

A
washing soda

B
bleaching powder

C
caustic soda

D
lime soda

Solution

Washing soda or sodium carbonate is used for removing permanent hardness of water.

Question 3

1 / -0

Match the following columns:

Column (I)	Column (II)
(1) Bleaching powder	(a) Sodium bicarbonate
(2) Baking soda	(b) Sodium carbonate
(3) Washing soda	(c) Calcium oxychloride
(4) Plaster of Paris	(d) Calcium sulphate hemihydrate

(1) $$\rightarrow$$ (c), (2) $$\rightarrow$$ (a), (3) $$\rightarrow$$ (b), (4) $$\rightarrow$$ (d)

(1) $$\rightarrow$$ (a), (2) $$\rightarrow$$ (b), (3) $$\rightarrow$$ (c), (4) $$\rightarrow$$ (d)

(1) $$\rightarrow$$ (b), (2) $$\rightarrow$$ (c), (3) $$\rightarrow$$ (d), (4) $$\rightarrow$$ (a)

(1) $$\rightarrow$$ (d), (2) $$\rightarrow$$ (a), (3) $$\rightarrow$$ (b), (4) $$\rightarrow$$ (c)

Solution

Bleaching powder $$\longrightarrow$$ Calcium oxychloride $$-\ CaO{Cl}_2$$

Baking soda $$\longrightarrow$$ Sodium bicarbonate $$-\ NaHCO_3$$

Washing soda $$\longrightarrow$$ Sodium carbonate $$-\ Na_2CO_3$$

Plaster of Paris $$\longrightarrow$$ Calcium sulphate hemihydrate $$-\ CaSO_4\cdot \dfrac12H_2O$$

Question 4
1 / -0

pH of pure water is__________.

A
$$0$$

B
$$1$$

C
$$7$$

D
$$14$$

Solution

Pure water is tasteless,odorless,colorless and neutral in nature with $$pH\: 7$$.
Question 5
1 / -0

Metal carbonates and hydrogen carbonates react with acids to give :

A
carbon dioxide gas

B
hydrogen gas

C
sulphur dioxide gas

D
carbon monoxide gas

Solution

Carbonates reacts with mineral acids to form carbon dioxide gas which gets evolved from the reaction mixture.
Question 6
1 / -0

Sodium chloride is known as:

A
rock salt

B
common salt

C
table salt

D
all of the above

Solution

Sodium chloride is known as rock salt, common salt, table salt.
Question 7
1 / -0

In soda-acid extinguisher, the bottle contains:

A
$$H_2SO_4$$

B
$$NaHCO_3$$

C
$$NaOH$$

D
$$HCl$$

Solution

In a soda acid fire extinguisher, concentrated sulfuric acid reacts with sodium hydrogen carbonate to produce carbon dioxide, sodium sulfate and water.
$$2NaHCO_3 + H_2SO_4 \Rightarrow 2CO_2 + Na_2SO_4 + 2H_2O$$

Thus Option A is correct.
Question 8
1 / -0

If $$pH$$ of a solution is $$13$$, it means that it is:

A
weakly acidic

B
weakly basic

C
strongly acidic

D
strongly basic

Solution

Solution with $$pH= 13$$ is a strong base as the basicity increases from $$7$$ to $$14$$. At $$pH = 7$$ it is less basic and moving to $$14$$ it increases.
Question 9
1 / -0

Sulphurous acid turns ________.

A
blue litmus into red

B
red litmus into blue

C
no change to any of the litmus paper

D
can't say

Solution

Sulphurous acid $$(H_2SO_3)$$ is an acid. The main use of litmus is to test whether a solution is acidic or basic. Blue litmus paper turns red under acidic conditions. So sulphurous acid turns blue litmus into the red.
Question 10
1 / -0

Non-metals + acids $$\rightarrow$$

A
slow reaction

B
violent reaction

C
moderate reaction

D
no reaction

Solution

Nonmetals do not react with acids, Thus, option $$D$$ is correct
