Question

Match List I with List II

List I		List II
A	Slaked lime	I	$NaOH$
B	Dead burnt plaster	II	$Ca(OH)_2$
C	Caustic soda	III	$Na_2CO_3 10H_2O$
D	Washing soda	IV	$CaSO_4$

Choose the correct answer from the options given below:

• (A) - III, (B) - IV, (C) - II, (D) - I
• (A) - III, (B) - II ,(C)- IV, (D) - I
• (A) - I, (B) - IV, (C) - II, (D) - III
• (A) - II ,(B)- IV,(C)- I, (D) - III

Answer 1

The Correct Option is D

 To solve this problem, we need to match the compounds from List I with their corresponding chemical formulas from List II. Let's break down each item in List I:

1. Slaked lime: The chemical formula for slaked lime is \(Ca(OH)_2\). It is commonly used in chemistry and construction. Hence, it matches with II.
2. Dead burnt plaster: This refers to anhydrous calcium sulfate, which has the chemical formula \(CaSO_4\). It is used in plastering and design. Hence, it matches with IV.
3. Caustic soda: This is the common name for sodium hydroxide, which has the chemical formula \(NaOH\). Sodium hydroxide is a strong base used in various chemical industries. Hence, it matches with I.
4. Washing soda: This is better known as sodium carbonate decahydrate, with the formula \(Na_2CO_3 \cdot 10H_2O\). It is commonly used in cleaning products. Hence, it matches with III.

Given these matches, we can determine the correct option:

A	-	II
B	-	IV
C	-	I
D	-	III

Thus, the correct option is:

(A) - II, (B) - IV, (C) - I, (D) - III
