Given information
The given acids are needed to be ranked in the order of decreasing strength in acid.
Step-by-step explanation
Step 1.
Solution A is a type of binary acid solution, and its dissociation is shown as:
This is a complete dissociation, hence the given acid HA is a strong acid.
Solution B depicts some of the undissociated molecules of acid HA, whether some are dissociated to form and ions.
This shows this acid HA is a mild acid.
Solution C depicts that all the molecules of the given acid HA are in undissociated form. Hence, the acid in this solution is a weak acid.
