Sorry for being a little nosy, but what are you using the NaHSO4 for? If you have H2SO4, then there are almost no use of NaHSO4 that you can't replace
with H2SO4. The only ones I could think of is the production of SO3, which is very dangerous and should only be attempted by experienced chemists,
with the proper equipment (makeshift equipment cannot withstand SO3) But you don't need NaHSO4, FeSO4 can be used for that instead. Another use is the
production of various bisulfates and pyrosulfates, which doesn't have much use themselves save of being converted into SO3. There is no source on the
internet, but I would think that non-alkaline/alkaline earth metal pyrosulfates/bisulfates are unstable/cannot be formed at all.
Hi there Welming. No you are not being nosy, I have recently gone into copper and silver and pewter art, not so much jewelry as design. I have made
beautiful tonal blues from various combinations of chemicals - oxidation basically of the copper metal. I need the sodium bisulphate as a replacement
for jewelers pickle solution, basically it destroys all oxidations after annealing (heat treatment). Also it is an ingredient in a japanese patina
which can not be bought outside of japan, though I have read otherwise recently.
I love chemistry and it was my favourite subject at school many many years ago. But like a lot of things in life, one does not always end up on the
chosen path. Now after many years I find myself in the silver and copper art design area and it involved many chemicals. I have an investigative
mind and so am never satisfied with a result - Ineed to understand. Hence funny as though it sounds I enjoy making chemicals and will try to avoid
buying them. Most of the acetates and carbonates I have made myself - but I never needed the maths, I did it the 10th century way - eyes only without
the maths. But with some chemicals I need to get it precies, and I wanted to understand the moles and atomic weights - but you know, when you are 53
you have had to learn so much technical stuff and apply yourself to adapting so much through the years that learning yet another skill can be
exhausting, especially with a family and other work.
Kind regards
