Please help?!

if 600 mL of a 0.04M KCl solution is mixed with 50mL of a 0.03M Na2SO4 solution, will a precipitate be formed? Explain your reasoning and/or show all calculations?

1 answer

No ppt. There are essentially three reasons for a reaction to occur.
1. A ppt is formed
2. A gas is formed.
3. A slightly ionized substance si formed.

KCl, Na2SO4, K2SO4 and NaCl all are soluble so #1 will not occur.
2. None of the four possibilities is a gas so #2 will not occur.
3. All of the four listed above are strong electrolytes which leaves #3 out.
Therefore, no reaction, no pt, no nothing except mixing of the two solutions.
