How do i solve this precipitate question?

Separate the ions Cu2+, Ag 1+, Sr 2+, one ion at a time by adding
something that will form a definite precipitate with only one of the ions being separated.
The process is continued until all ions have been separated

chmvijay · Answer

first add to solution contain Cl- anion then Ag + will precipitate and other two ions wont precipitate
then separate the precipitate now u have solution congaing only Sr and CU

chmvijay · Answer

then add solution SO4_2 ions in this case Sr will precipitate as Sr2SO4 and other mean Cu wont get precipitated just separate the SrSO4 ppt and now all are separated
