Question

Match the following

	Column (A)		Column (B)
(a)	$NaHC{O}_3$	(i)	Caustic soda
(b)	$N{a}_{2}C{O}_3.10H_{2}O$	(ii)	Baking soda
(c)	$NaOH$	(iii)	Blue vitriol
(d)	$CuS{O}_4.5H_{2}O$	(iv)	Washing soda

• A. a-(i), b-(ii), c-(iii), d-(iv)
• B. a-(ii), b-(iv), c-(i), d-(iii)
• C. a-(i), b-(iv), c-(ii), d-(iii)
• D. a-(ii), b-(iv), c-(iii), d-(i)

Answer 1

The correct option is B a-(ii), b-(iv), c-(i), d-(iii)

$NaHC{O}_3⟶$ Baking soda (Sodium Bi-carbonate)

$N{a}_{2}C{O}_3\cdot 10H_{2}O⟶$ Washing soda (Sodium carbonate deca-hydrate)

$NaOH⟶$ Caustic soda (Sodium hydroxide)

$CuS{O}_4\cdot 5H_{2}O⟶$ Blue vitriol (Copper sulphate pentahydrate)

Hence, option $B$ is correct.
