Needle like crystals
After, displacing tin, copper and nickel with zinc.
And then precipitated Zn+2 with NaHCO3.
Solubility of NaHCO3 are very low.
When soluted, it drops as nice white light weight powder.
This time I droped few spoons powdered baking soda.
Completely different reaction, white grey gel precipitated.
Decomposed sample to black carbon looking substance.
Ok solutions of many batches, combined in one. And evaporated.
First NaCl looking cubic crystals dropped out.
Then filtered solution crystallized as cactus pin like crystals.
What is it?

Dirty ore, what precipitated with zinc, will be redissolved.
And tin purified to light green powder, with ammonia solution.
Living smelly copper and nickel complex.
When decomposed to brown, will carbon reduce Sn? If so would any of C go in alloy with it?
