[Histonet] eosin pH

[Rene J Buesa]

The eosin should be acidic and you get to that point adding 1% aq. sol. of acetic acid to you prepared solution, at a rate of 1 mL acetic/100 mL of eosin solution.

Hi!
Can someone tell me the right pH for eosin y 1% aqueous solution?
The one I made from powder has pH 6.3. Is this OK? The commercial one we 
usually buy is a bit lower (5.7).
Thank you in advance!
Hana Peter
