Question

vant hoff factor explain..

Answer 1

Van't Hoff factor is the the value which is used when a electrolytes or non electrolytes colligative properties is changed when they are dissolving in any aqueous solutions

Answer 2

Van't Hoff factor:- This is a relationship which tell us about relationship between colligative properties which is normal & abnormal colligative properties. It is donated by i.

$\sf{i = \frac{Number \: of \: particles \: after \: dissociation \: or \: association}{Number \: of \: particles \: after \: dissociation \: or \: association} } \\ \\ \sf{i = \frac{Observed \: collgatve \: properties }{Calculated \: colligative \: properties}} \\ \\ \sf{i = \frac{Calculated \: molecular \: mass}{Observed \: molecular \: mass} }$

Possible cases:-

• If i = 1 [Neither dissociation nor association] Examples:- glucose, urea, sugar etc.

• If i > 1 [There will be dissociation] Examples:- NaCl, KCl, BaCl2 etc.

• If i < 1 [Association will occur]. Examples:- CH3COOH, PhCOOH in benzene etc.
