Question

Identify the products of the reaction between 2KOH and H₂SO4.

O KSO and H2₂O
OK2SO4 and H₂O
O H₂O and K₂SO4
O KH2 and SO4

Answer 1

C.) H₂O and K₂SO₄

Step-by-step explanation:

This appears to be a double-displacement reaction. In these reactions, the cation of one substance is swapped with the cation of another.

So, K⁺ from KOH is swapped with the H⁺ from H₂SO₄. The new compounds should have an overall charge of 0. Therefore, it may be necessary to modify the amount of each ion (not just be 1:1).

K₂SO₄
-----> K⁺ and SO₄²⁻

-----> + 1 + 1 + (-2) = 0

H₂O

-----> H⁺ and OH⁻

-----> + 1 + (-1) = 0
