Ammonium carbonate ((NH4)2CO3) is a specific reagent that precipitates the cations of group 2 in qualitative analysis. It forms insoluble carbonates with cations such as calcium, strontium, and barium, allowing for their separation from other cations in the group.

What is the group precipitant of group 1 cations?

The group precipitant of group 1 cations is dilute hydrochloric acid (HCl). When added to a solution containing group 1 cations, it precipitates them as chlorides, which can then be further identified through specific confirmation tests.


Another reagent that could be used in place of HCL to precipitate cations of the silver group?

Another reagent that can be used to precipitate cations of the silver group is hydrochloric acid (HCl).


What is the reagent used for group 2?

Group 2 reagents are used for the identification of cations such as calcium, strontium, and barium. Common reagents include ammonium carbonate, ammonium oxalate, and ammonium sulfate.


What is group reagent?

How might cations in group 1 be separated from cations in group 2?

If your Group 2 cations are calcium, strontium or barium, add a solution containing sulphate ions, i.e. sulphuric acid or the sulphate of the Group I metal that is the Group I cations in your solution. The Group 2 cations will precipitate out with the sulphate ions. If you have beryllium or magnesium cations, then I don't know.


Why are the group 1 cations removed as insoluble chlorides?

Group 1 cations (Li+, Na+, K+) are removed as insoluble chlorides (LiCl, NaCl, KCl) because they form stable and insoluble precipitates with chloride ions in acidic solutions. This precipitation process allows for the separation of group 1 cations from other cations present in the solution.


Which anion forms soluble compounds?

Anions that form precipitates are solutions that are combined to form an insoluble ionic solid. The reactions of cations and anions to form precipitates will vary depending on the temperature, solutions for buffers or solution concentration.


What two cations commonly form precipitates?

Silver (Ag+) and lead (Pb2+) cations commonly form precipitates when they react with anions such as chloride or sulfate ions. These reactions result in the formation of insoluble salts, which appear as precipitates in solution.


Is group 7A cations?

Group 7A cations refer to the cations of Group 7A elements in the periodic table, also known as the halogens. Some common examples of Group 7A cations include fluoride (F-), chloride (Cl-), bromide (Br-), and iodide (I-).
