Question

Assertion: Anhydrous ${{H}_{2}}S{{O}_{4}}$ undergoes autoprotolysis ${{H}_{2}}S{{O}_{4}}+{{H}_{2}}S{{O}_{4}}\rightleftharpoons {{H}_{3}}S{{O}_{4}}^{+}+HS{{O}_{4}}^{-}$
Reason: Anhydrous ${{H}_{2}}S{{O}_{4}} has very high electrical conductivity.

Answer 1

Hint: Acids are generally those substances which are capable of donating a proton i.e. hydrogen atom to another substance while bases are those substances which are able to accept a hydrogen ion from an acid.

Complete answer:
Acids are generally sour in taste and it turns blue litmus paper to red. Bases are bitter in taste and turn red litmus paper into red. A base that can be dissolved in water is known by the term alkali and when these substances chemically react with acids they form salts.
is known as sulphuric acid it can accept protons as well as donate protons where protons are defined as the positively charged ions as it can accept or lose protons so it is known to be amphoteric in nature. Due to this reason it undergoes autoprotolysis by the reaction as shown:
${{H}_{2}}S{{O}_{4}}+{{H}_{2}}S{{O}_{4}}\rightleftharpoons {{H}_{3}}S{{O}_{4}}^{+}+HS{{O}_{4}}^{-}$
This reaction shows that one atom is losing protons and another is accepting the proton. Hence we can say that anhydrous ${{H}_{2}}S{{O}_{4}}$ undergoes autoprotolysis.
Anhydrous ${{H}_{2}}S{{O}_{4}}$ contain hydrogen ions as well as sulphate ions. Hence it has very high electrical conductivity.
Thus we can say that both assertion and reason are true statements but reason is not the correct explanation of assertion.

Option B is the correct answer.

Note:
If equal amounts of strong acid and an equal amount of alkali are reacting with each other then the rise in temperature will remain the same. This is because of the fact that the amount of energy released per gram will be the same.
