Storage of indicator solution
« on: November 29, 2015, 11:22:05 PM »
Hi everyone,

I would like to know which indicator is light sensitive and required special storage (eg. dark place, amber bottle) after I prepare the solution?

1. Phenolphthalein
2. Bromothymol Methyl Blue
3. Methyl Red
4. Chlorophenol Red.

Thanks in advance.
