A solution was known to contain both Ag1+ ions and Fe3+ ions? Which of the following could be added to separate them in such a way that one ion would end up in a precipitate, while the other remained in solution.
Group of answer choices
K2CrO4
HCl
NH4OH
H2O
Homework Answers
In inorganic qualitative analysis, first we need to identify the cation to which group it belongs.
Out of two ions present in the solution, Ag+ is Group I cation, Fe3+ is a Group III cation.
First given solution containing silver and Ferric ions is treated with dilute HCl. Silver ions precipitated as it's chloride. Ferric ions remain in the solution. It is due to Solubility product of AgCl is greater than its ionic product. Where as for ferric ion Solubility product is greater than its ionic product.
When HCl is added, all the silver ions are precipitated.
Hence HCl is the answer.

Purpose: To calculate the amount of AgNO3 present in an unknown solution of water through the process of gravimetric analysis with NaCl. Background: Have you ever had difficulty lathering soap or find that the scum in your shower constantly needs to be removed? These are signs of “hard water.” Soap does not lather well in hard water because metal ions, such as Ca2+, form precipitates, creating “soap scum.” A precipitate is an insoluble compound that forms when soluble ions in...
