Van’t Hoff Factor (i) worksheet
The measure of the solute upon vapour pressure, osmotic pressur and freezing point depression is called Van’t Hoff Factor (i). It is the ratio between the actual concentration of a particles of dissolved substance and the concentration of the substance as calculated from its mass. The van’t factor for non-electrolytes dissolved in water is usally 1. Here you can find some questions related to Van’t Hoff factor (i) and it’s answer: Questions: 1. The benzoic acid undergoes dimerization in benzene solution, the van’t...

A homogenous mixture composed of only one phase is known as solution. A solute is dissolved in another substance, which is known as solvent. The solvent takes part in dissolving. Solubility is defined as the ability of a compound to dissolve another compound. The physical properties of the compound change when another compound is added to it. In this article you can find some questions related to “Solutions” and their answers: Questions: 1. For preparing a litre N / 10 solution we need (a) 10 gm (b) 4.9 gm (c) ...

Solution obtains when solutes are dissolved in solvents. Solvent is present in greater quantity and solute is present is less amount. The amount of solute dissolved in a unit volume of solution is the concentration of the solute. In this article you can find some questions related to Nature of solution and their answers: Questions: 1. The physical state of solution can be: (a) solid (b) always liquid (c) liquid, solid or gas (d) none of these 2. when a saturated solution of sodium chloride is heated, it...

When the freezing point of a liquid is lowered down by using another compound, Freezing point depression occurs. The solution has the lower freezing point.For example, the freezing point of seawater is lower than that of pure water. Here, you can find some questions related to Freezing point depression and their answers: Questions: 1. Find the volume of a solution having 1 mol of sugar and an osmotic pressure of 1 atm at : (a) 11.2 litre (b) 2.24 litre (c) 22.4 litre (d) 112 litre 2. The osmotic pressure of 0.2 molar...

The pressure which is applied to a solution to prevent the inward flow of water across a semipermeable membrane is known as Osmotic pressure. Pressure which is required to stop osmosis is called Osmotic pressure. In this article you can find some questions related to Osmotic pressure and their answers: Questions: 1. Which of the following chemical entities can act as semipermeable membrane? (a) (b) (c) (d) None of these 2. 0.5 M aqueous solution of glucose is isotonic with: (a) 0.5 M CaCl2 solution (b) ...

Raoult’s law was discovered by Fransois-Marie Raoult in 1882. This law states that, ” The vapour pressure of an ideal solution is dependent on the vapour pressure of each chemical component and the mole fraction of the component present in the solution.” In this article you can find some questions related of Raoult’s law & Vapour pressure , with their answers: Questions: 1. The lowering of vapour pressure of the solvent takes place: (a) only when the solute is a non-electrolyte (b) only when the solute is...
