Except it, all r negative.

Answer 2

Answer:

The positive sol amongst the given sols is the $TiO_2$ sol.

Explanation:

As we have already learned, positively charged sols are mainly metal hydroxides and metal oxides.

On the other hand, the negatively charged sols are mostly metal sulfides.

This is, of course, one of the electric properties of the sol, and is based on the presence of a kind of excess charge. Usually, the charges are balanced by the dispersion medium and the dispersed phase, which makes the colloid neutral.

But, the charge on the sol makes it stable by making the colloidal particles repel each other due to common charges.
