Statement I : For colloidal particles, the values of colligative properties are of small order as compared to values shown by true solutions at same concentration.
Statement II : For colloidal particles, the potential difference between the fixed layer and the diffused layer of same charges is called the electrokinetic potential or zeta potential.
In the light of the above statements, choose the correct answer from the options given below
Given below are the critical temperatures of some of the gases:
Gas | Critical temperature (K) |
---|---|
He | 5.2 |
CH$$_4$$ | 190.0 |
CO$$_2$$ | 304.2 |
NH$$_3$$ | 405.5 |
The gas showing least adsorption on a definite amount of charcoal is
$$100 \mathrm{~mL}$$ of $$5 \%\,(\mathrm{w} / \mathrm{v})$$ solution of $$\mathrm{NaCl}$$ in water was prepared in $$250 \mathrm{~mL}$$ beaker. Albumin from the egg was poured into $$\mathrm{NaCl}$$ solution and stirred well. This resulted in a/an :
Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R
Assertion A : Thin layer chromatography is an adsorption chromatography.
Reason R : A thin layer of silica gel is spread over a glass plate of suitable size in thin layer chromatography which acts as an adsorbent.
