← A cell filled with a weak monobasic acid of concentration 0.36 mol/L has a conductance of 0.96 mS. The acid is diluted to 0.090 mol/L and the same cell is used. The acid is so weak that α varies as 1/√c. What is the new conductance?Four statements are made about conductance. I. The molar conductivity of a weak electrolyte tends to its limiting value as the concentration goes to zero. II. The molar conductivity of a strong electrolyte does not change with the concentration. III. The conductivity of a strong electrolyte falls when its solution is diluted. IV. The limiting molar conductivity of a weak electrolyte is found by extending a straight line of Λm against √c. Which statements are correct? →
