Question

Match the column I with column II and mark the appropriate choice.

	Column I		Column II
(A)	$N{a}_{2}C{O}_3$	(i)	Caustic soda
(B)	$NaOH$	(ii)	Glauber's salt
(C)	$N{a}_{2}C{O}_3.10H_{2}O$	(iii)	Soda ash
(D)	$N{a}_{2}S{O}_4.10H_{2}O$	(iv)	Washing soda

• A. $\left(A\right)\to \left(iv\right),\left(B\right)\to \left(i\right),\left(C\right)\to \left(ii\right),\left(D\right)\to \left(iii\right)$
• B. $\left(A\right)\to \left(iv\right),\left(B\right)\to \left(i\right),\left(C\right)\to \left(iii\right),\left(D\right)\to \left(ii\right)$
• C. $\left(A\right)\to \left(ii\right),\left(B\right)\to \left(iii\right),\left(C\right)\to \left(iv\right),\left(D\right)\to \left(i\right)$
• D. $\left(A\right)\to \left(iii\right),\left(B\right)\to \left(i\right),\left(C\right)\to \left(iv\right),\left(D\right)\to \left(ii\right)$

Answer 1

The correct option is D $\left(A\right)\to \left(iii\right),\left(B\right)\to \left(i\right),\left(C\right)\to \left(iv\right),\left(D\right)\to \left(ii\right)$

${Na}_{2}C{O}_3$ is commonly known as Soda ash.
