Question:
The number of positively and negatively charged sols respectively in the following are:
TiO\(_2\), blood, CdS, Cu, Ag, Clay, SiO\(_2\), Fe\(_2\)O\(_3\)
The number of positively and negatively charged sols respectively in the following are:
TiO\(_2\), blood, CdS, Cu, Ag, Clay, SiO\(_2\), Fe\(_2\)O\(_3\)
TiO\(_2\), blood, CdS, Cu, Ag, Clay, SiO\(_2\), Fe\(_2\)O\(_3\)
Show Hint
Charge on sol particles depends on adsorption of ions and the nature of the colloid.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Classify sols.
Positively charged sols: TiO\(_2\), Fe\(_2\)O\(_3\), Ag, Cu
Negatively charged sols: SiO\(_2\), Clay, CdS, blood
Step 2: Count.
Positively charged = 4, negatively charged = 4
Step 3: Conclusion.
\[ \boxed{4, 4} \]
Positively charged sols: TiO\(_2\), Fe\(_2\)O\(_3\), Ag, Cu
