You will get marks by ecf. For tests, i tested for O2 in black solid, and when they asked to test with litmus paper, they had provided us with red litmus paper and i observed no change in litmus paper.ok, i identified the iodide wrng, do you think i'll get the ecf for the nxt part where we had to mention the observation with H2SO4?
how many marks do u think i'll lose for that?
and one more thing, did you guys test the gases that were formed while we were testing FA5 and FA6?
ya also test 4 O2 but i wrote the glowing splint relights is that right?? and i obseved bleaching in the litmus paper... it tuens white ..
but what about the O2 was it evovled?
for the identification maybe 2 and 4 the table it was 4i tested for O2 as well.
and we got both blue and red litmus paper and the blue one turned red and then bleached. i wrote the observation but i didn't say it was chlorine.
oh, and do u remember how many marks were allocated for the halide identification?
