Weak electrolytes equation The graph of Λ c versus C 1/2 shows that the equivalent conductance of weak electrolyte decreases exponentially with concentration so that equivalent conductance at infinite dilution ( Λ o) for weak electrolyte can not be determined from the above curve on extrapolation. Although such substances as ordinary salt and hydrogen chloride are strong electrolytes—i. Weak elec&oly’s$ What is a weak electrolyte? Weak acid (every acid that’s not a strong acid) Examples: CH 3COOH, HNO 2, HF, HCN HCN + H 2O H 3O+ + CN-Weak bases (every other base) Example: NH 3 NH 3 + H 2O NH 4 + + OH-system lies very far toward reactants K (equilibrium constant very small 4 x 10-10) Water is also considered to be a weak electrolyte. Solutions of electrolytes. α = √ K b × V. So, we can say that the degree of dissociation of a weak electrolyte is inversely proportional to the square root of molar concentration or directly proportional to the volume. Correct Statements:(B) Value of the constant A depends upon the In a solution, the molecules of a weak electrolyte are in equilibrium with its ions. Examples: Weak acids and weak bases are weak electrolytes. Strong electrolytes ionize completely (100%), while weak electrolytes ionize only partially (1–10%).
