Question
. How could you detect the presence of the Ag' ion? Complete and balance the following equations: LiCl(s) + H2SO4 (aq)- NH, (aq) + OH-(aq): AgNO3(aq) +1-(aq)- NaHCO3(s) + H' (aq)- Why should distilled water be used when conducting chemical tests? Assume that you had a mixture of solid Na CO, and NaCI. Could you use only H2SO4 to determine whether Na CO, was present? Explain. . Assume that you had a mixture of solid Na,CO, and NaCI. How could you show the presence of both carbonate and chloride in this mixture? How could you show the presence of both iodide and sulfate in a mixture? Consult Appendix C for help.Explanation / Answer
ANSWER:-An easy chemical test is to add a solution containing chloride
ion (sodium chloride solution works) to the solution you think
contains the silver (Ag+) ion. If it does contain silver, a white
precipitate of silver chloride will form and sink to the bottom.
As a further confirmation, the precipitate will dissolve in
ammonium hydroxide solution (ammonia water).
If it is in solution, you can react it with potassium iodide and then AgI would crash out. this detects for the Ag+ ion.
