Current Question (ID: 9129)

Question:

$\text{Common table salt becomes moist and does not pour easily in rainy season because:}$

Options:

1. $\text{It contains magnesium chloride.}$
2. $\text{It contains magnesium carbonate.}$
3. $\text{It melts slightly in rainy season.}$
4. $\text{Sodium chloride is hygroscopic.}$

Solution:

$\textbf{HINT:} \text{ } \text{MgCl}_2 \text{ is hygroscopic.}$ $\textbf{Explanation:}$ $\text{Table salt is sodium chloride and some minute quantities of magnesium chloride.}$ $\text{These salts are hygroscopic in nature resulting in absorbing moisture from the surroundings so it becomes sticky during rainy season.}$ $\text{Thus, common table salt becomes moist and does not pour easily in rainy season because of } \text{MgCl}_2$
