Answer to Question #314634 in General Chemistry for Abby

Question

Aqueous solutions of potassium hydrogen sulfate and potassium hydroxide react to form aqueous potassium sulfate and liquid water. How many moles of potassium hydroxide are necessary to form 0.636 moles of potassium sulfate?

Answer 1

The equation is below:

KHSO₄(aq) + KOH(aq) --> K₂SO₄(aq) + H₂O(l)

$n(KOH)=0.636\ mol(K_2SO_4)\times\frac{1\ mol(KOH)}{1\ mol(K_2SO_4)}=0.636\ mol$

Answer: 0.636 mol
