Solved An aqueous solution of ammonia is found to be basic
An aqueous solution of ammonia is found to be basic. This observation can be explained by the net ionic equation An aqueous solution of ammonia is found to be basic. This observation can be explained by the net ionic equation NH4+(aq) + H2O(l) → NH3(aq) + H3O+(aq).
Solved Learning Goal: To learn how to calculate ion | Chegg.com
Learning Goal: To learn how to calculate ion concentrations in an aqueous solution of a strong diprotic acid. Sulfuric acid, H2SO4, is a strong acid. Its complete dissociation in aqueous solution is represented as H2SO4→H++HSO4− A HSO4− anion can dissociate further by HSO4−⇌H++SO42− but the extent of dissociation is considerably ...
