<u><em>Answer:</em></u>The compound ammonia given by fish is alkaline
<u><em>Explanation:</em></u><u>We can classify elements/compounds based on their pH values into three types:</u>
<u>acids:</u> these are compounds having pH value lower than 7
<u>neutral:</u> these are compounds having pH value equal to 7
<u>alkalies:</u> these are compounds having pH values higher than 7
This is shown in the attached image
We are given that the pH of the compound ammonia generated by the fish is
above 7.
According to the above explanation, compound ammonia would be an alkaline compound.
Hope this helps :)</span>
