Which of the following are correct statements
(A) Δ G = Δ HD - T Δ BS < O as Δ S < 0 so Δ H has to be negative
(B) Micelles formation will take place above T k and above CMC
(C) This solution will be negatively charged.
(D) Fe3+ ions will have greater flocculatibility power so smaller flocculating value.
11.19 Which of the following statements are true for physisorption?
11.20 Which of the following are incorrect statements ?
In gel, liquid is dispersed in solid,
11.21 The origin of charge on colloidal solution is
Adsorption is the presence of excess concentration of any particular component at the surface of liquid or solid phase as compared to bulk. This is due to presence of residual forces at the surface
of body. In the adsorption of hydrogen gas over a sample, of charcoal, 1.12cm3 of H2(g) measured over S.T.P. was found to adsorb per gram of charcoal. Consider only monolayer adsorption. Density of H2 is 0.07gm/cc. In another experiment same 1 gm charcoal adsorbs 100m1 of 0.5M CH3COOH to form monolayer and thereby the polarity of CH3COOH reduces to 0.49.
