Identify Conjugate Acid Base Pairs

Cohabit Acid-Base Pairs

Below are some molecular representations of various acids (the water molecules take been left out). Which best represents an aqueous solution of hydrogen cyanate (HOCN, a weak acrid)?

HOCN is a weak acid and will partially ionize in aqueous solutions.

Expert! Since HOCN is a weak acid, both HOCN and OCN^- will be in solution.

HOCN is a weak acid and will but partially ionize in aqueous solutions.

The chemic equation representing the reactions occuring in a hydrogen cyanate solution is:

The double arrow in the above equation represents an equilibrium. This ways in the solution, both the forward and backward reactions are occurring. It is important to realize that in this solution, reactions are ever occuring; reactions do not finish after equilibrium is reached. Under the magnifying glass below you can see a representation of the molecules nowadays in this solution.

Click on magnifying glass to see a reaction occur. Clicking once more volition evidence another reaction.

In this representation, you can observe the acidic nature of the HOCN molecule, that is you can see it donate a proton to h2o. The reverse reaction shows the basic nature of the OCN^- ion; you can see information technology have a proton from the hydronium ion.

HOCN and OCN^- are an instance of a conjugate acid-base pair. The just deviation betwixt the two is a proton (H⁺).

All acids accept a conjugate base and all bases have a conjugate acid.

From the list of molecule/ion pairs below, click on those that are conjugate acid-base pairs.
