Sugar and salt solutions are categorized as true solutions.
In chemistry, a true solution is a homogeneous mixture where the solute (like sugar or salt) is completely dissolved in the solvent (typically water) at the molecular level. This results in a clear, uniform mixture where the solute particles are not visible to the naked eye and do not settle upon standing. The key characteristics of true solutions include:
These characteristics distinguish true solutions from heterogeneous mixtures, colloidal solutions, and suspensions, where the phases are either visibly distinct, or the particles differ in size and behavior.
A substance 'X' (1.5 g) dissolved in 150 g of a solvent 'Y' (molar mass = 300 g mol$^{-1}$) led to an elevation of the boiling point by 0.5 K. The relative lowering in the vapour pressure of the solvent 'Y' is $____________ \(\times 10^{-2}\). (nearest integer)
[Given : $K_{b}$ of the solvent = 5.0 K kg mol$^{-1}$]
Assume the solution to be dilute and no association or dissociation of X takes place in solution.
Consider the following statements: Statement I: \( 5 + 8 = 12 \) or 11 is a prime. Statement II: Sun is a planet or 9 is a prime.
