Chemical Reactions of Cations X3, Y2, and Z
What are the results of the chemical tests for cations X3, Y2, and Z?
1. What happens when Na2SO4 is added to X3, Y2, and Z solutions?
2. What is the reaction between Z (aq) and Na2SO4?
Results of Chemical Tests:
1. When Na2SO4 is added: - X3: No Reaction - Y2: Forms white ppt. - Z: Brown ppt. forms
2. The reaction between Z (aq) and Na2SO4: - Forms a brown ppt.
Chemical Equations and Explanations:
To represent the reactions that result in the formation of precipitates, we can write the following balanced chemical equation:
- For Z and Na2SO4 reaction:
[tex]2Z^+ (aq) + SO^{2-}_4 (aq) = Z_{2}SO_{4}[/tex]
Explanation:
The formation of a brown ppt. when Z(aq) reacts with Na2SO4 indicates the formation of a solid product. Since Z+ is monocationic and SO4 is dianionic, 2 molecules of Z+ will combine with 1 molecule of SO4, leading to the balanced chemical equation shown above.
