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 .......    

Text Solution

Verified by Experts

The correct Answer is:
1
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`.
