Question

fish give off the compound ammonia which has a PH above 7. To which class of compounds does ammonia belong?

Answer 1

Answer: Ammonia is considered as a base.

Explanation:

pH is defined as the negative logarithm of hydrogen or hydronium ion concentration that are present in a solution.

The equation representing pH of the solution follows:

$pH=-\log[H^+]$

pH range of the solution varies from 0 to 14.

There are 3 types of solution: acidic, basic and neutral

• If the pH of the solution is from 0 to 6.9, the solution is said to be acidic.
• If the pH of the solution is from 7.1 to 14, the solution is said to be basic.
• If the pH of the solution is 7, the solution is said to be neutral.

We are given:

Ammonia has a pH above 7. So, this compound is a basic compound.

Hence, ammonia is considered as a base.

Answer 2

The class of compounds that ammonia belongs to is it is categorized as a basic compound. As it posses a pH value or rating above 7, which is characteristic of basic substances, solutions.
