In the qualitative analysis scheme for metal ions, how are the analytical group iii cations separated from the cations of analytical groups iv and v? a. by addition of hcl, forming insoluble metal chlorides b. by addition of h2s in basic solution, forming insoluble metal sulfides or hydroxides c. by addition of h2s in acidic solution, forming insoluble metal sulfides d. by addition of (nh4)2co3 or (nh4)3po4, forming insoluble metal carbonates or phosphates e. by addition of h2so4, forming insoluble metal sulfates

it is stable as it is in group 0 which have full outer shells of electrons

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
