Consider following statement :- (a) Molarity depends on temperature (b) Molality does not depend on temperature (c) On dilution, concentration of solution will be increased (d) Sum of the mole fraction of all the components present in a solution are unity Which statements are correct?

Options

  1. AStatement (A ) and (B ) are correct, (C ) and (D ) are incorrect
  2. BStatement (A, B, C ) are correct, (D ) are incorrect
  3. COnly statement (A ) is correct, (B, C, D ) are incorrect
  4. DAll are correct statements

Correct answer

A. Statement (A ) and (B ) are correct, (C ) and (D ) are incorrect

Step-by-step solution

(a) Molarity depends on temperature. - This statement is correct. Molarity is defined as moles of solute per liter of solution, and since volume can change with temperature, molarity can vary with temperature. (b) Molality does not depend on temperature. - This statement is correct. Molality is defined as moles of solute per kilogram of solvent, and this measurement is not affected by temperature, as mass does not change with temperature. (c) On dilution, the concentration of solution will be increased. - This stat
