Hello in this problem we are asked in Equus solution which of the following behaves is a strong acid or a strong base. We call that strong acids and strong bases associate completely unique ways. Solution an example of a strong acid is hydrochloric acid. Hydrochloric acid associates completely to form hydrogen ins and forward irons. And an example of a strong base is sodium hydroxide, sodium hydroxide also dissociates completely form sodium mines and hydroxide annan's. So we don't have that many strong acids. We have. Seven strong acids are strong acids include hydrochloric acid, hydrochloric acid, hydrochloric acid. And so these are somewhat easy to remember and that they all contain a halogen. Then we have nitric acid. We have our one die protic acid sulfuric acid. We have per caloric acid and then boric acid. So that's it. Strong bases. These are hydroxide to contain a group one a metal cast iron or the heavier group to a metal cast irons. So examples would be sodium hydroxide, potassium hydroxide etc from group one A and they have your group to a so strong sham hydroxide and barium hydroxide. If we go back to the list that were provided above, we were given per caloric acid boric acid which was on our list of strong acids. So this is a strong acid. We were given a church to S. 03 which is sulfurous acid. This is a weak acid sulfuric acid is the strong acid. We are given ammonia ammonia is a weak base. And the last one we were provided was bromide, ramadi is the on ticket base by strong acid formic acid, but it is not a strong base. So within this list we only have a single strong acid, which is coric acid. We have no strong base in the list. Thanks for watching. Hope. This helps.
