Following are equimolal aqueous solutions :
Arrange them in increasing (i) boiling point

Options

A. 1m urea
B. 1m KCl
C. `1m Mg Cl_2`
D. `1m Na_3 PO_4`

Explanation

To solve the problem of arranging equimolar aqueous solutions in increasing order of boiling point, we will follow these steps:

### Step 1: Understand Colligative Properties
Colligative properties depend on the number of solute particles in a solution rather than the identity of the solute. The boiling point elevation (ΔTB) can be expressed as:
\[ \Delta T_B = i \cdot K_B \cdot m \]
Where:
...
