Sodium thiosulfate is one of the few know substances that will dissolve silver bromide. As such it is universally used in modern photographic procedures.

In this process known as "fixation," the unexposed silver bromide is dissolved in the sodium thiosulfate by combining with it to form soluble complex thiosulfates of silver and sodium.

Very Satisfied!!!!!

Comments about Photographers' Formulary Sodium Thiosulfate (Hypo) Penta (Prismatic Rice) - 1 Lb.:

I'm an illusionist and was needing to find a way of getting a larger quantity of this chemical. And the price could not be beat! The product I received was just what they said it would be. I will be placing all my orders in the future with B&H as well as refer my photographer friends to them!

    Sensitivity of the fix is obviously dependent on the solvent. Works just as it should-- price is as cheap as Bostick & Sully..
