chemical formula for potassium hydrogen sulfide? is it KHS?

yes

Yes, the chemical formula for potassium hydrogen sulfide is indeed KHS. The formula tells us the types and number of atoms present in a compound. To determine the formula for potassium hydrogen sulfide, we need to consider the charges of the ions involved.

Potassium is a metal in Group 1 of the periodic table, and it has a +1 charge when it forms ions. Sulfur is a nonmetal in Group 16, and it generally forms ions with a -2 charge. Hydrogen, in this case, can have a +1 charge.

To balance the charges between the potassium and the sulfide ion, we need one potassium ion (K+) and one hydrogen sulfide ion (HS-) to form a neutral compound. This results in the chemical formula KHS.

So, in summary, the chemical formula for potassium hydrogen sulfide is KHS, as it reflects the balance of charges between potassium (+1) and hydrogen sulfide (-1).
