Which is a lyophilic colloid?

Last Updated:

This SSC CGL Chemistry question asks: “Which is a lyophilic colloid?” The correct answer is Starch sol. Starch sol is lyophilic because dispersed phase has affinity for dispersion medium. Option A (“Gold sol”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question. Option B (“Sulphur sol”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question. Option D (“Arsenious sulphide sol”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question.

AGold sol
BSulphur sol
CStarch sol
DArsenious sulphide sol
Correct Answer: Starch solYour Answer: C

Explanation

Option A (“Gold sol”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question. Option B (“Sulphur sol”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question. Option D (“Arsenious sulphide sol”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question. The answer field, correct index and explanation therefore all identify Starch sol. Starch sol is lyophilic because dispersed phase has affinity for dispersion medium.

FAQ

SSC CGL Chemistry FAQs

Common questions and clear answers for this topic.

How many chemistry questions typically appear in the SSC CGL exam?

Chemistry usually contributes a handful of questions within the General Awareness section, generally covering basic concepts rather than calculation-heavy problems.

Which chemistry topics are most important for SSC CGL preparation?

Atomic structure, periodic table trends, acids-bases-salts, metals and non-metals, and carbon compounds are the areas that appear most consistently across past papers.

Is NCERT chemistry enough to prepare for SSC CGL?

NCERT textbooks from classes 9 and 10 cover most of the conceptual base needed, though supplementing with general knowledge about everyday chemical compounds helps too.

What is the best way to remember chemical reactions and formulas for SSC CGL?

Linking reactions to real-world examples, like rusting or antacids, makes them easier to recall than memorizing formulas in isolation.

Does the SSC CGL chemistry syllabus overlap with the school board syllabus?

Yes, a large part of the syllabus mirrors class 9 and 10 science, making school-level revision a practical starting point.
