Can someone suggest me the recipe for making Eosin solution from eosin y (sigma;dye content 99% ). I followed the recipe - 1gm Eosin in 20ml water and 80ml 95% ethanol but the eosin powder is not dissolving.
Yair Botbol I looked online and apparently eosin y (sigma;dye content 99% ) is not soluble in water. I now use Eosin Y disodium salt (sigma) which is soluble in water.
