Good video man!!! It really helped me! Thanks!
I think before d addition of dil HCl bacl2 should come first to detect and dil HCl to confirm
They said a retort stand sir and not two retort stands
Do you watch the video finish ? This is not the exact question waec will give you. Is just the likely question they can ask on the specimen given.
Sir can you do a video on how to tie a thread to the metre rule that’s my problem here but u skipped it
I have the video here... Check my uploaded videos you will see it
