Question

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?

Answer 1

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

Answer 2

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

Answer 3

@oOKawaiiOo

Answer 4

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

Answer 5

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

Answer 6

To show that Ba is more soluble in solution than Zn

Answer 7

so whats the equation for this reaction?

Answer 8

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

Answer 9

what's the purpose of the HCl then?

Answer 10

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

Answer 11

hmmm ok
