Complete and balance each of the following equations. K2SO4(aq)+BaBr2(aq)→

Would it be K2SO4(aq)+BaBr2(aq)→K2Br2 +SO4Ba?
Express your answer as a chemical equation. Enter no reaction if no precipitate is formed.
(How can we know if a solid is formed in the product?)

I have a problem with the answer. Most is right but the equation should be

K2SO4(aq) + BaBr2(aq) ==> 2KBr(aq) + BaSO4(s).
Note: KBr is soluble; BaSO4 is not.
Next question is how do you know when a solid is formed. The answer is you memorize a set of solubility tables. Here is a simplified set.

I suggest you confirm from this table that KBr is soluble and BaSO4 is not.

K charge of +1

B charge of +2
SO4 charge of -2
Br charge of -1
to get the solution swap the charges.
mixing to ionic solution when mixing the metals switch places
so you get KBr and BaSO4
which is also K1Br1 Ba2(SO4)2
since the charges are the same you don't write them.
K2SO4= K2(SO4)1 BaCl2=Ba1Cl2 when the charge is one you don't write it.

Can you show me how you finished the equation?

Express your answer as a chemical equation. Enter noreaction if no precipitate is formed.

Answer:
K2SO4(aq)+BaBr2(aq)→2KBr(aq)+BaSO4(s)

To determine if a solid is formed in the product, we need to check whether a precipitate is produced during the reaction. A precipitate is a solid substance that forms when two solutions are mixed together.

In this case, we can use solubility rules to identify if a precipitate is formed. Solubility rules are guidelines that tell us which compounds are soluble (dissolve) in water and which ones are insoluble (form a solid precipitate).

For potassium sulfate (K2SO4), it is a soluble salt. Additionally, barium bromide (BaBr2) is also soluble. So when these two solutions are mixed together, no solid precipitate is formed.

The balanced equation for the reaction is:
K2SO4(aq) + BaBr2(aq) → no reaction

Therefore, there is no solid formed in the product.

K2SO4(aq)+BaBr2(aq)→ 2KBr(s)+ 2BaSO4(aq)

formation of a salt when the solution mix.
