Question

Which of the following ion has greater coagulating power for negatively charged sol?

• A. $Fe(CN)_{6}^{4-}$
• B. $PO_{4}^{3-}$
• C. $Ba^{2+}$
• D. $Al^{3+}$

Hint:

Chemistry Tip: The coagulating power order for negative sols is typically $Al^{3+}>Mg^{2+} / Ba^{2+}>Na^{+} / K^{+}$. The effect increases exponentially with charge.

Answer 1

The Correct Option is D
