Identify the acid-base pairs in the following reactions HSO4^1-(aq) + OH^1- <==>SO4^2-(aq) + H2)(I)
It should be obvious that one pair is HSO4^- and SO4^2-
The other pair, not quite so obvious, is OH^- and H2O (HOH). But if you pick out the HSO4^/SO4^2-) you know what's left is the other pair. Most questions of this type don't stop here but want to know which is the acid and which the base. Here is how you tell which is which. The ACID is the one with the extra H. The base is the one with the fewer H.
So for the HSO4/SO4, HSOr must be the acid and SO4 must be the base.
In OH/H2O, the OH has fewer H and the H2O has more H so which is which.
Well, I must say, that reaction is quite a tongue twister! But fear not, I can still help you with your question. In this reaction, the acid-base pairs are as follows:
Acid: HSO4^- (aq)
Base: OH^- (aq)
The acid, HSO4^-, donates a proton, while the base, OH^-, accepts a proton. They are separated by the double-headed arrow indicated in the reaction equation. So, in this case, HSO4^- is the acid, and OH^- is the base.
To identify the acid-base pairs in the given reaction, we need to identify the substances that donate or accept protons (H+ ions).
In the reaction: HSO4^-(aq) + OH^-(aq) <==> SO4^2-(aq) + H2O(l)
The acid-base pairs are as follows:
1. Acid: HSO4^-(aq)
Base: OH^-(aq)
2. Acid: SO4^2-(aq)
Base: H2O(l)
So, the acid-base pairs in the reaction are HSO4^-(aq) and OH^-(aq), as well as SO4^2-(aq) and H2O(l).
To identify the acid-base pairs in a reaction, you need to understand the concept of acids and bases. Acids are substances that donate protons (H+) or accept electrons, while bases are substances that accept protons (H+) or donate electrons.
In the given reaction: HSO4^1-(aq) + OH^1- <==> SO4^2-(aq) + H2O(l)
We can see that HSO4^- is the acid, as it donates a proton (H+) to OH^-. On the other hand, OH^- is the base, as it accepts a proton (H+) from HSO4^-.
So the acid-base pairs in this reaction are:
HSO4^- (acid) + OH^- (base) <==> SO4^2- (conjugate base of acid) + H2O (conjugate acid of base)
Note: Conjugate acid-base pairs are formed when an acid loses a proton and becomes a conjugate base, or when a base accepts a proton and becomes a conjugate acid.
