Question

define concentration of solution.

Answer 1

Concentration of solutions generally means the amountof solute or solvent present in it if the solute is more the solution is said to be concentrated if the solvent is water and the amount of of solvent which is water is more then that of solute then the solution is said to be dilute...

Answer 2

Concentration of a solution:

Concentration of solution depend on number moles of solute particles in solution.

• Mass percentage of solute (Weight/Weight). Mass of the solute present in 100 parts by mass of solution mass % of solute = Wb / Wa + Wb x 100

• Volume percentage of solute (v/v). Volume of solute present in 100 parts by volume of solute. Volume % of solute = Vb / Va + Vb x 100

• Mass / Volume percentage of solute = Wb / Vsolution x 100. Mass of solute present in 100 parts by volume of solution.

• Parts per million Short form ppm Mass of solute present in million parts by mass of solution.

• Mole fraction of solute: It is the ratio of number of moles of solute and solvent. Xb = nB / nA + nB xA + xB = 1
