Solution
12. In a solution the solvent is present in more quantity and is a gas or a liquid.
So option D is correct.
13.The Bronsted - Lowry Theory of acids and bases .,A base is a proton (hydrogen ion)
acceptor.
An Arrhenius base is a substance that, when dissolved in an aqueous solution, increases the
concentration of hydroxide, or OH-, ions in the solution.
Here HSO3- is a Bronsted base but not Arrhenius base
Therefore option D is correct.
14.In this water can accepts a proton to produce H3O+ so it is a Bronsted-Lowery base.
So option E is correct.
15.A congugate acid-is base pair is the one which differs by a proton that is H+.
In the given set of options all are correct which differs by a proton so option E is correct.
