Tyndall effect is observed in

Last Updated:

This SSC CGL Chemistry question asks: “Tyndall effect is observed in” The correct answer is Colloids. Tyndall effect (scattering of light by colloidal particles) is observed in colloids like milk starch solution fog. Chemistry explains the composition, structure, properties and transformations of matter. A reliable answer begins by identifying whether the question concerns atomic structure, chemical bonding, periodicity, stoichiometry, acids and bases, redox chemistry, electrochemistry, organic nomenclature, metallurgy or everyday materials. Formulae and equations must be interpreted rather than memorised without context. Numerical problems require the correct molar mass, unit conversion and significant figures. Redox questions should identify oxidation as electron loss or increase in oxidation number and reduction as electron gain or decrease in oxidation number.

ATrue solutions
BColloids
CSuspensions
DBoth colloids and suspensions
Correct Answer: ColloidsYour Answer: B

Explanation

served in colloids like milk starch solution fog. Option A (“True solutions”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question. Option C (“Suspensions”) 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 (“Both colloids and suspensions”) is incorrect because it does not satisfy the chemical formula, reaction, periodic trend, numerical relation, oxidation state or definition required by the question. Identify the governing formula, definition or reaction and apply it consistently. The answer field, correct index and explanation therefore all identify Colloids. Tyndall effect (scattering of light by colloidal particles) is observed in colloids like milk starch solution fog.

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.
