CHXII05:SURFACE CHEMISTRY

320875 When dilute aqueous solution of \(\mathrm{AgNO}_{3}\) (Excess) is added to KI solution, positively charged sol particles of \(\mathrm{AgI}\) are formed due to adsorption of ion

1 \(\mathrm{K}^{+}\)
2 \(\mathrm{Ag}^{+}\)
3 \(\mathrm{I}^{-}\)
4 \(\mathrm{NO}_{3}^{-}\)
CHXII05:SURFACE CHEMISTRY

320876 The coagulation values of \(\mathrm{AlCl}_{3}\) and \(\mathrm{NaCl}\) are 0.093 and 52 respectively. Then coagulating power of \(\mathrm{AlCl}_{3}\) as compared to that of \(\mathrm{NaCl}\) is

1 \(52 \times 0.093\) times
2 \(52 / 0.093\) times
3 \(0.093 / 52\)
4 \(0.093 / 52\) times
CHXII05:SURFACE CHEMISTRY
