Can I use Sodium Borohydride in the reversal bath instead of potassium borohydride? If so what sort of adjustment?


edta na 4 is EDTA Tetrasodium?
yes you can substitute metol.

Uh...are you sure it is sodium borohydride? Sodium borohydride is water reactive, it will generate a flame. You better make sure this is the right ingredient.

yes Na4 is EDTA tetrasodium.
