- A Metal sol, -ve
- B Metal sol, +ve
- C Metal sulphide sol, -ve
- D \(\mathrm{TiO}_2\) sol, +ve
Answer & Solution
Correct Answer
(A) Metal sol, -ve
Step-by-step Solution
Detailed explanation
Bredig's Arc (Electrical disintegration) method is used to prepare colloidal sals of metals such as gold, silver, platinum etc... In this method, electric arc is struck between electrodes of the metal immersed in the dispersion medium. The intense heat produced vapourises the…
