Indicate what precipitates if any form when solutions of eac

Indicate what precipitates, if any, form when solutions of each of the following are added to a solution containing the Group I cations. Write net ionic equations for the precipitation reactions that occur. Use Ksp table.

a. HBr (aq)

b. H2S04 (aq)

c. Na2C03 (aq)

Solution

C.precipitate will ocour in form of carbonate of the group ! cation present

2Ag+ + Na2CO3 -----> Ag2CO3 + 2Na+

ksp Na2CO3 is very large hence it will remain in dissolved form

ksp of Ag2CO3 is 1.8*10^-12 as it is very less Ag2CO3 will precipititate
