What is the formula for a barium chloride solution reacts with sodium sulfate solution to produce solid barium sulfate and sodium chloride in a solution?
The reaction is:
BaCl2 + Na2SO4 + BaSO4(s) + 2 NaCl
If both are in solutions, barium sulfate would precipitate out of the solution - unless if the barium chloride solution is dilute enough that only a small amount of barium sulfate will form, thus remaining soluble in the solution. The remaining sulfate will remain in the solution as wellas sodium and chloride.
