Sulfamates
Hi today i made copper sulfamate dihydrate. Also I will make Ni and Co sulfamates. It has beautiful deep blue colour. I used basic copper carbonate
and sulfamic acid, next i evaporated solution.

You should make chromium sulfamate
Nuclear physics is neat. It's a shame it's so regulated...
Now that I think about it, that's probably a good thing. Still annoying though.

I have no clue about the color. Chromium tends to make nice colors though

Nice! The first time I tried making copper sulphamate, I accidentally heated it, so it hydrolyzed and the only precipitate I got was ammonium
bisulphate.
Please remember: "Filtrate" is not a verb.

If you ever want to electroplate lead, its sulphamate is very water soluble. I have used a lead anode in sulphamic acid for this purpose. The color
of that salt isn’t particularly interesting though.

I have heard of nickel being actively used, but I have not heard of lead. thanks.

You're welcome! For a chemist should give all for another chemist's sake- he should give flask for flask- love as a road and a bridge!

Nice blue Vano. Sulfamates are also on my list to make one day.

I made a bunch of sulfamates in the past. The Ni salt is extremely hygroscopic and you will get a viscous oil that takes a lot to dry. The Co salt
gives a very hard crust. The Mn(II) salt is a dirty white solid.

Thanks for sharing your experience. Did you ever tried chromium salt?

Hi, today i made cobalt sulfamate hydrate, thats is why it has light pink colour. I made it from cobalt carbonate and sulfamic acid.
When the water evaporated from the solution to the end, it had exactly the same color as Valleg sulfamate, it was also really hard to crust. So I
redissolved it in water, then heated it, when some of the water had evaporated and left a pink solid that looked wet, I removed the bottom of the
flask and transferred it to its walls. After a few minutes it dried with the help of hot air and got a similar color, unfortunately I do not know the
formula of hydrate.
It contains some anhydrous blue particles, i will be made better powder.
