What can be added to a solution of Cu2 (aq) Mg2 (aq) and Sr2 (aq) ions to precipitate the Sr2 (aq) ions but not the others?

Add a sodium hydroxide solution; copper and magnesium hydroxides are insoluble. Strontium hydroxide is low soluble.

When a precipitation reaction occurs the ions that do not form the precipitate?
A precipitation reaction is usually a double displacement reaction. The ions that do not form the precipitate usually form the solution.
What substance adds or removes Hydrogen ions from a solution?
metals and salts that precipitate it - e.g silver nitrate would remove OH ions from solution. Acids would also tend to remove OH ions from solution
What precipitate is produced when aluminum sulfate and barium chloride react?
Since barium chloride is reactive with sulfate ions there would be more precipitate present. The solution with more precipitate present would show it had higher amounts of sulfate ions
Do HCl and ferric nitrate form a precipitate?
Nope. All ions would stay in solution.
How can you obtain sulfur?
Adding a Oxidizing agent to a solution of S2O32- ions precipitate out white sulfur.
What can be added to a solution of OH- (aq) S2- (aq) and SO42- (aq) ions to precipitate the OH- (aq) ions but not the others?
Add a solution of magnesium chloride; magnesium hydroxide is not soluble in water.
When a precipitation reaction occurs the ions that do not form the precipitate?
A precipitation reaction is usually a double displacement reaction. The ions that do not form the precipitate usually form the solution.
How do you test for bromide ions?
Add silver nitrate solution to a solution of bromide ions. A pale yellow precipitate of silver bromide formed indicates the presence of bromide ions.
What is the test for barium ions?
Gives white precipitate when Sulfuric acid added!
What is the test reagent for chloride ion?
The most common one is a solution of silver nitrate, which forms a white precipitate of silver chloride when added to a solution containing more than a minute concentration of chloride ions.
What substance adds or removes Hydrogen ions from a solution?
metals and salts that precipitate it - e.g silver nitrate would remove OH ions from solution. Acids would also tend to remove OH ions from solution
What is a term meaning to come out of solution?
I don't know the context of the solution but I believe in this case it means for ions to precipitate out. For example, when barium hydroxide (Ba(OH)2) is added to sulfuric acid (H2SO4) in aqueous solution, the ions will disassociate and barium sulfate (BaSO4) will form a solid from the Ba and the SO4, thus "come out of solution."
Could copper also cause zinc ions to precipitate?
No. Ions do not precipitate on their own. Since zinc is more reactive that copper it will replace copper. So placing zinc in a solution of a copper salt will cause elemental copper to precipitate.
What precipitate is produced when aluminum sulfate and barium chloride react?
Since barium chloride is reactive with sulfate ions there would be more precipitate present. The solution with more precipitate present would show it had higher amounts of sulfate ions
I woke up this morning with a solution next to my bed and assumed it was a cationic solution and added some HCl to it which didn't produce a precipitate and flame test was pale green so what is in it?
My friend, it would appear you have a solution containing barium ions. If you would like add some sulfuric acid to precipitate the barium as barium sulfate.
Do HCl and ferric nitrate form a precipitate?
Nope. All ions would stay in solution.
