Question

Which of the following occurs when equal volumes of 0.01 M SrCl2 and 0.01 M CuSO4 are mixed?

Select one:
a.A precipitate does not form.
b.A precipitate of SrSO4 forms.
c.A precipitate of CuCl2 forms.
d.Precipitates of SrSO4 and CuCl2 form.

Answer 1

a. A precipitate does not form.

Step-by-step explanation:

To determine the outcome when equal volumes of 0.01 M SrCl2 and 0.01 M CuSO4 are mixed, we need to consider the possible precipitation reactions based on the solubility rules.

The solubility rules state that most chloride (Cl-) salts are soluble, except when paired with silver (Ag+), lead (Pb2+), or mercury (Hg2 2+) ions. On the other hand, sulfate (SO4 2-) salts are generally soluble, except when paired with barium (Ba2+), strontium (Sr2+), or lead (Pb2+) ions.

Given that SrCl2 is soluble and CuSO4 is soluble, we can conclude that when these two solutions are mixed, no precipitate will form.
