as level practical

If you have a question that asks you according to the task 2 for example, how can you confirm that lets say iodine is present you where suppose to write a yellow precipitate in task 2 but you didn't write that. How do you answer that? You write the correct answer or the one you got on your experiment? HELP!

Correct answer unless it really didn't look yellow, then it could be cream and be bromine and if your really unlucky it could be white and be chlorine. So try to remember what it actually looked like!

Ohh thanks you don't know how confused I was:-D

I got white but I think I made a mistake as everyone else got yellow

Was that cation tests? I remember doing that..

The test for chloride, bromide and iodide ions involves observing the ppt formed when silver nitrate is added.

Chloride forms white, bromide forms cream and iodide forms yellow.

These colours are usually difficult to distinguish without comparison.

This, dilute and concentration ammonia is added to the ppt.

Chloride ppt (AgCl) dissolves in both dilute and conc. Bromide ppt (AgBr) dissolves only in conc. Iodide ppt (AgI) dissolves in neither.

Thus, if you had iodide ions, you would notice a yellow ppt in addition of silver nitrate which wouldn't dissolve on addition of dilute or conc ammonia.

Yep go with what they got, it was probably yellow good luck

It was for halogens I think and I'm writing the paper tomorrow

guys any ideas for what solution A was?
