Yeah Usually it is used to test for Iodide, but in this case this was ingeniously used to test for Lead.
@d!_†oX!©:
OK!!!!!!!!!!!!
so d yellow colour actually shows d presence of lead!!!!!!!
ohh
dts cool...didn't know dat!!!
so this provees that the salt is lead carbonate!!!!
By the way eightAs have u seen a test for lead anywhere else except here???it isn't there in the qualitative analysis notes as well!!

No it isn't there. During the pre-boards, when we had to do this thingee. I was thinking of the significance of (d). Then I picked up the notes page, looked at all the cations first, no luck. When went to the anion section, I saw the test for Iodide. The yellow ppt thing clicked and I realized it was lead. Tough, I didnt do well in it either cos the chemicals in our school were *******. I couldnt even see limewter going milky, there was just a faint precipitate.
