Let's discuss this question.
00:02
So here the question is that we need to fill up the table and answer the questions below.
00:07
Here, ions are given to us.
00:08
We need to write the confirmatory reagents and the observations.
00:12
Second question says that what ions are the member of group 2 ket ions? third option is like for each of the following peers identify a reagent that will dissolve one substance but not the other.
00:23
And the last question says that explain the theoretical aspects of separation of group 2 a, cat ions from group to be an ion.
00:32
So here first we have hg 2 plus ions.
00:34
So this hg 2 plus ions, the conformatory reagent for this will be h2s or hcl.
00:42
And here the observation will be white ppp, white precipitation of hgs.
00:51
Now we have as3 plus ion, that is arsenic ion.
00:54
So here we can say h2s and hcl is the conformatory reagent.
00:59
And here the observation will be yellow ppt of as2 s3.
01:08
Then we have sb 3 plus.
01:11
So here h2s and hcl will be the conformatory reagent and here the observation will be orange ppt, that is orange precipitates of sb2s3.
01:25
Then we have bi3 plus so here the conformatory reagents will be h2s and hcl and here the observation will be brownish black ppt of b i 2 s 3 then we have c u 2 plus so here the conformatory reagent is h2s and hcl and here the observation will be black ppt of c u s then we have h2s and hcl is also the conformatory reagents of cadmium ions and here the observation will be yellow ppt of cds.
02:19
Then we have s and 2 plus ions and here the confirmatory reagent is h2s and hcl and here we can say brown precipitation of sns is observed over here...
