    Thiocyanate: Sodium Versus Potassium

    Hi All,

    I've found a formula for a E-6 colour first developer that uses potassium thiocyanate. However, I have sodium thiocyanate on hand. Are the two exchangeable for this purpose? My gut feel says they are but I don't want to presume that is the case.

    Any thoughts?

    Yes. You must adjust the amount of salt based on molecular weight though.

    Understood. Thanks for the confirmation. I'll have to add 20% more Sodium Thiocyanate.
