Hello everyone in this question first they have done flame test with colorless unknown solution they have done flame test from flame film film test they got bright yellow color they got bright yellow color bright yellow color so this indicates that the unknown solution contains sodium ions they contain sodium ions they contain sodium ions they contains sodium ions.
00:34
So when sodium ions present in the solution when that solution is subjected to flame test will get bright yellow color.
00:41
This indicates the solution containing sodium ion that is n a n a ions.
00:47
After that what happens when that sodium ions that that solution is going to be treated with a.
00:55
So in a x here x is we have to find out here n a x is treated with ag no3 will get precipitated that means ag x plus n -a -n -o -3.
01:11
Here ag x is precipitated.
01:15
This indicates that x might be chloride or carbonate co3, 2 minutes.
01:28
So ag cell is also formed precipitate and at the same time, cell.
01:33
Silver carbonate that is ag co3 2 months also form precipitate in next step what what they done is when when h .cl added added to that added to that colorless solution that colorless colorless solution it forms it forms it forms it forms bubbles it forms so this indicates that the solution contains co3 2 minus...
