What is the chemical formula for ammonium sulfate?

The chemical formula of ammonium sulfate is

Explanation:

Ammonium sulfate is a salt which is formed by the combination of two polyatomic ions which are ammonium and sulfate ions.

The chemical formula for ammonium ion is and the chemical formula for sulfate ions is

By criss-cross method, the oxidation states of the ions becomes the subscripts of the other ions.

Hence, the chemical formula of ammonium sulfate is

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
