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 .......
The no.of H_(3),O^(+) ions present in 10 ml of water at 25^(@) C is
When 1.0 xx 10^(-5) mg of a protective colloid is added to 20 ml of standard gold sol, the precipitation of gold sol was prevented by adding 5 ml of 10% solution of NaCl. If the gold number of protective colloid is 2.0 x 10^(-x) mg then x is = __?
One gram of a protective colloid 'X' is to be added to 200ml of gold sol to prevent coagulation of it when 20 ml of 10% NaCl is added. Calculate the gold number of protective colloid 'X'.
When 11.2 g of KOH is added to one litre of 'X' M H_(2) SO_(4) solution , the pOH of the solution becomes 13.301 . Then the value of 'X' is (assume no change in the volume of solution by the addition of KOH)
A magnetic field of ( 4.0 xx 10^(-3)hatk) T exerts a force ( 4.0hati + 3.0hatj ) xx 10^(- 10) N on a particle having a charge 10^(-9) C and moving in the x-y plane. Find the velocity of the particle.
