How can you detect the presence of the SO4-2?
Firstly add some AgNO3. You should see that no precipitate forms. If it forms a precipitate, it is not a SO42-.Then add some BaCl2 - If there are SO42- ions a white precipitate will form.
Another reagent that could be used in place of HCL to precipitate cations of the silver group?
HNO3 which forms white precipitate..
What is the role of KI in the estimation of aniline?
ki is added to liberate iodine gas . this liberated iodine gas was then titrated with sodium thiosulphate to give a permanent white precipitate. this white precipitate indicates the endpoint of the titration..
What is an example of the formation of a precipitate?
Formation of a precipitate is evidence of a chemical reaction.
What ion is most likely present in water tested with silver nitrate that gave a white precipitate?
It is chloride which forms silver chloride.
What is the colour of silver thiocyanate?
AgSCN forms a white precipitate in water.
What is a example of formation of a precipitate?
an example of a precipitate is: silver nitrate + sodium chloride = silver chloride and sodium nitrate the precipitate is the silver chloride it forms a white powder
What is the test for barium ions?
Gives white precipitate when Sulfuric acid added!
Aqueous solutions of Barium Nitrate and Sodium Hydroxide are combined Does a precipitate form?
Yes a white precipitate forms when these two solutions are combined.

What is observed when sodium sulphate solution is added to barium chloride?
White precipitate of barium sulphate
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 is observe when aqueous ammonia is added in excess to a silver chloride solution?
The white precipitate of silver chloride will dissolve when aqueous ammonia is added.
When solutions NACl and AgNO 3 are mixed what precipitate forms?
NaCl(aq) + AgNO3(aq) = AgCl(s) + NaNO3(aq) - so the precipitate is white silver chloride.
What would you see when acidified silver nitrate solution is added to a solution of Low sodium salt?
White precipitate.
