KSCN vs NaSCN

Hello,

currently researching on making my own BW developer for E6 process and there is a line in a recipe which states the use of NaSCN. As I imagine that the chemical is used to reduce grain in the film (also as thiosuphate).
The question is can I replace NaSCN with KSCN? The darkroom cookbook states that NaSCN is a substitute for potassium thiocyanate weight for weight. Can I do the same in reverse order?


TIA,
Justas

Thiocyanate is a halide solvent; its use in reversal first developer is mainly to produce clear highlights (and at higher concentrations, it can overall lighten the slide).

That said, if one is a sub for the other weight for weight, it shouldn't matter which direction you're substituting.

Yes, you can, but not weight for weight. You need to use equimolar amounts. Multiply NaSCN weight by 1,2 to get the equimolar amount of KSCN.
