Which is more powerful to coagulate the negative colloid?

View answer and explanation

Correct option: C

\mathrm{AlC}{\mathrm{l}_3}

Option C (

\mathrm{AlC}{\mathrm{l}_3}

) is correct because, according to the Hardy-Schulze rule, the ion with the highest charge will be the most effective in coagulating a negative colloid.

Al^{3+}

has the highest positive charge among the options.
