Per NCERT, the VOLUME BY VOLUME percentage (% v/v) is used when which condition holds?
ABoth solute AND solvent are miscible LIQUIDS — e.g. alcohol in water, vinegar, perfumes
BOne is solid and the other is liquid
CBoth are gases at room temperature
DBoth are solids
Answer & Solution
Correct answer: A. Both solute AND solvent are miscible LIQUIDS — e.g. alcohol in water, vinegar, perfumes
% v/v is for liquid-in-liquid solutions (per NCERT formula 5.3). The other options misstate the use case.
