Answers
assertion reason type....
The correct answer is : (B) Both assertion and reason are correct but reason is not the correct explanation of assertion
A : Aerated drink contains carbon dioxide gas as solute and water as a solvent .
aerated drinks are also called soft drinks or carbonated drinks. In these drinks, carbon dioxide is dissolved in water making water a solvent and carbon dioxide a solute.
Thus, the assertion statement is correct.
R: Air is a mixture of gas in gas which main constitutes is oxygen 21% and nitrogen 78%
Air is a mixture of gases as properties of each of the gases present in air retains its properties. The main constituents of air are certainly nitrogen and oxygen with 78 % and 21% respectively.
Hence, the reason statement is also correct.
However, the dissolution of carbon dioxide in water is the reason carbon dioxide gas is solute and water is solvent.
