my 0.5 m/L sodium bromide solution has gone clear yellow (used to be clear)

can I rescue it? can it be used as it is?

Hi Rainbow Sky, and our wonderfull Chemtalk family.

Sodium Bromide is a bit like Hydrochloric Acid. It will turn yellow under prolonged storage under artificail light.

Natural light will speed up this process but the NaBr is still useable.

Cheers,

Thanks Robb

The prac that I wanted it for was for the light reaction. so from what you are saying...thinking now its best NOT to use a soln thats yellow to begin with?
