Which option has both statement and reason correct?
Answer and explanation
Correct answer: Statement: Soda water is a liquid solution. Reason: Its solvent is liquid
Soda water contains carbon dioxide dissolved uniformly in water. Water is the solvent and is liquid, so the overall solution is classified as a liquid solution; it is also an aqueous solution. The presence of a gaseous solute does not make the whole solution gaseous. Air is a gaseous solution and brass is a solid solution, so their classifications in C and D are wrong. Therefore A has both a correct statement and a valid reason.
