What factor proves that a soluble salt is made? NOTE: The salt produced in the experiment was ZnSO4. When the HCl and BaCl2 solution was added, the mixture turned to a milky substance. Taking this into consideration, what was the factor?

Read the question again. You cant make ZnSo4 from HCl and BaCl2

oh...but, what factor, in general, proves that a soluble salt is made?

The compound that had a lower Ksp will precipitate out of solution which was the ZnCl2, when HCl and BaCl2 was added. ZnCl2 wasnt presented in the solution before. So you can assume a reaction had occurred. The more soluble salt is dissolved in the solution

so what was the purpose of adding the HCl and the BaCl2 to the mixture containing distilled water and ZnSO4???

To show that Ba is more soluble in solution than Zn

so whats the equation for this reaction?

ZnSO4(aq) + BaCl2(s) --> ZnCl2(s) + BaSO4(aq)

what's the purpose of the HCl then?

I think its the common ion effect, to precipate ZnCl2 out solution at a faster rate.
