D-85 substitution with potassium bisulfite ?

[jfdupuis]

Hi,

The other day, I wanted to try to do some lith print. Therefore, I grab the D-85 formula and look at my chemical closet. I have everything in hand except the sodium bisulfite. However, I have plenty of potassium bisulfite. Can I use it as a substitution for the D-85 ?

Thanks,

Jeff

Jeff;

Assuming that both salts are anhydrous you can use them in a ratio of 1.16g KHSO3 to 1g NaHSO3.

P.S. Thats the molar ratio, remember that from chemistry?
