Which of the following is the correct chemical formula for ammonium hydrogen sulfate?
A
NH4HSO4
B
NH4SO3
C
NH4SO4
D
NH4HSO3
Verified step by step guidance1
Identify the ions involved in ammonium hydrogen sulfate. The ammonium ion is \(\mathrm{NH_4^+}\), and the hydrogen sulfate ion (also called bisulfate) is \(\mathrm{HSO_4^-}\).
Recall that ammonium hydrogen sulfate is a salt formed by the combination of the ammonium cation and the hydrogen sulfate anion.
Write the formula by combining one ammonium ion \(\mathrm{NH_4^+}\) with one hydrogen sulfate ion \(\mathrm{HSO_4^-}\), ensuring the charges balance to zero.
Since both ions have charges of +1 and -1 respectively, they combine in a 1:1 ratio, resulting in the formula \(\mathrm{NH_4HSO_4}\).
Compare this formula with the given options to confirm that \(\mathrm{NH_4HSO_4}\) is the correct chemical formula for ammonium hydrogen sulfate.
