I have to apologize in advance for this but I have struck out on google and wherever else I could think to search including here. I would like mixing instructions for methyl orange in aqueous and organic media. Thanks,
CRX

For aqueous mix 1/10 to 1/2 gram of the solid M.O. with 1 liter of water, let it sit and draw portions from the top.
