A detergent [C_12 H_2SO_(4)^(-) Na^(+)] solution becomes a colloidal sol at a conc. of 10^(-3)M on an average 10^13 colloidal particles are present in lmm what is the average no.of ions are contain in one colloidal particle (micelle) no.of ions 6 x 10^x. x is .......

Answer»


Solution :No. of sodium lauryl sulpate in 1 lit solution : `10^(-3) xx 6 xx10^(23) = 6 xx10^20`
No. of Na lauryl sulphat PER MM `= 6 x 10^14`
No. of colloidal particles per mm `= 10^13`
No. of molecular per calloidal PARTICLE `(6 xx 10^(14))/(10^(13)) = 60`.
