When reacted with other elements or compounds it can release a huge amount of energy due to its high reactivity properties. We have two important theories to check whether H 2 SO 4 acid or not.
Arrhenius theory b. Bronsted-Lowry theory. Hence, it acts as an Arrhenius acid. This theory state that acid is the substance that donates the proton to other species and itself forms the conjugate base. For knowing whether H 2 SO 4 is a strong or weak acid, first, we have to understand what is a strong acid and weak acid.
Now, Is H 2 SO 4 strong acid or weak acid? There is no undissociated H 2 SO 4 present in the solution, it completely breaks off into the ions. To further understand Why H 2 SO 4 is a strong acid? And this reaction is irreversible means, it strongly favors the right side. In the second reaction, HSO 4 — as a weak acid that also partially dissociate and release the one proton and forms SO 4 The double arrow in the second reaction shows that both backward and forward reactions will occur at equilibrium.
Hence, this is why H 2 SO 4 is a strong acid in nature as it fully dissociates into ions in one shot. Also check:- How to know if acid or base is strong or weak? Yes, sometimes H 2 SO 4 can also act as a base if it reacts with superacids. A compound is said to be base when it accepts the proton or donates the OH — in an aqueous solution.
So, when sulfuric acid reacts with superacids then it will accept the proton from super acid, hence, act as a base. Also check:- How to tell if something is acid or base or salt? Lewis acid is a compound that accepts the pair of electrons and lewis base which donates the pair of electrons to other compounds. So, Is H 2 SO 4 lewis acid or base? To be a Lewis acid, the atom needs an empty orbital in its valence shell. Note: Lewis acid is a superset of Bronsted-Lowry acids that means every compound that falls into the category of Bronsted-Lowry acid is Lewis acids.
The acid will have both of these characteristics. Search titles only. Search Advanced search…. New posts. Search forums. Log in. Best of luck to the class of for their HSC exams. You can do it!
