What compounds can be formed by the reaction of K2SO4 and BaCI2?
In aqueous solution?
BaSO4(s) and KCl(aq)
To determine the compounds that can be formed by the reaction of K2SO4 (potassium sulfate) and BaCl2 (barium chloride), we need to examine the possible combination of the elements involved.
First, let's break down the compounds into their constituent ions:
K2SO4 → 2K+ + SO42-
BaCl2 → Ba2+ + 2Cl-
Now, we need to find a combination of ions that will result in a neutral compound. This can be achieved by exchanging the positive and negative ions. In other words, the positive ion from one compound combines with the negative ion from the other compound and vice versa.
In this case, the positive Ba2+ ion combines with the negative SO42- ion:
Ba2+ + SO42- → BaSO4
Therefore, the compound formed by the reaction of K2SO4 and BaCl2 is BaSO4 (barium sulfate).
So, the answer is: Barium sulfate (BaSO4) is the compound formed by the reaction of K2SO4 and BaCl2.
