How would I figure out the formula for Sodium Thiosulfate?
I was asked that question on an exam and I knew sodium sulfate was Na2SO4, so I figured ok, thio means sulfur, so I'll just add another S like this:
Na2S2O4
But my prof said Na2S2O3
was the right answer, and I have no idea how I was supposed to know there were only 3 O's, since it's not sulfite.
Wikipedia agrees with him, tho.
Any ideas?
