1.	Two solutions of X and Y electrolytes are taken in two beakers and diluted by adding 500mL of water. `Lambda_m` of X increases by 1.5 times while that of Y increases by 20 times, what could be the eletrolytes X and Y?A. X `to` NaCl , Y `to` KClB. X `to` NaCl , Y `to CH_3COOH`C. X `to` KOH, Y `to` NaOHD. X `to CH_3COOH` , Y `to` NaCl
Answer» Correct Answer - B Electrolyte X is strong electrolyte as on dilution the number of ions remain same , only interionic attraction decreases and hence not much increase in `Lambda_m` is seen . While `Lambda_m` for a week electrolyte increases significantly
