Trisodium Citrate
« on: March 07, 2019, 12:29:44 PM »
Now venturing into CG. Kephra's 'quick CG' hard to do here due to finding the gold chloride.

There appears to be a range of trisodium citrate termed 'E331' food grade.

E331 (i) Monosodium citrate
E331 (ii) Disodium citrate
E331 (iii) Trisodium citrate

Looking at https://bit.ly/2ToL2YO Is this ok?

thanks, tony

I used tri-sodium citrate.  I think it is the most common variant.
Colloidal Silver is only a bargain if you make it yourself.

@Kephra, in  Electrolysis-I  Gold process, you said Tri-sodium sitrate monohydrate to use, but i cant find it in my country anywhere, i only find TRI-SODIUM CITRATE DIHYDRATE which is the formula C6H5Na3O7.2H2O. Which has 294,10 g/mol molar weight.

Is it okay to use?

Yes, it's fine, but you will need to look up the molar weight of this, as it's sodium citrate dihydrate.

Molecular Formula: C6H9Na3O9
Average mass: 294.100 Da
