Which aqueous solution has higher concentration : 1 molar or 1 molal solution of the same solute. Give reasons.

Why is one molar solution more concentrated than one molal solutions ?

A molal solution is one that contains 1 mole of a solute in

Molality of the solution is

Define concentration of a solution. How is concentration of a solution expressed ?

Mole fraction of the solute in 1 molal aqueous solution is

Each question contains STATEMENT-I(Assertion) and STATEMENT-2(Reason).the statement carefully and mark the correct answer accoring to the instrution given below: STATEMENT - 1 : Isotonic solutions must hsve the same molal concentration. STATEMENT - 2 : Solution which have the same osmotic pressure are known as isotonic solution.

Resistance of a conductivity cell filled with a solution of an electrolyte of concentration 0.1M is 100 Omega . The conductivity of this solution is 1.29Sm^-1 . Resitance of the same cell when filled with 0.2 M of the same solution is 520Omega . The molar conductivity of 0.2 M solution of the electrolyte will be

Assertion: 0.1 M glucose solution has higher increment in the freezing point than 0.1M urea solution. Reason: K_f both has different values.

Two solutions A and B have pH 3 and 5 respectively. Which of the two solutions has more hydrogen ion concentration and which one is more acidic? Give reason for your answer.

Each question contains STATEMENT-I(Assertion) and STATEMENT-2(Reason).the statement carefully and mark the correct answer accoring to the instrution given below: STATEMENT - 1 : Osmotic involves movement of solvent molecules from lower concentration to higher concentration. STATEMENT - 2 : Solutions having the same osmotic pressure are called isotonic solutions.
