Talk:Sulfamic acid

Not enough information on chemical, especially ethylation reactions
I noticed there's not that much information on this molecule's chemistry, if it isn't wrong and ambiguous. The reactions with alcohols, notably ethanol, does not works on it's own and (probably) requires the urea; at least, on scales of 15% sulfuric acid and 98% EtOH. I've therefor changed that to match the experimental results. Another thing I noticed is that the similarities with ureas weren't very well documented; thus, i've added the decomposition reaction of sulfamic acid for clarity. --2A02:A03F:A91F:1300:806C:9E55:7F00:3EBA (talk) 17:00, 9 June 2020 (UTC)

Amino Acid Stabiliser
I recall reading somewhere that the addition of small quantities of sulfamic acid to amino acid solutions can help stabilise them in order to prevent decomposition during storage or transport. Sadly, I forget the details offhand. Can anyone kindly expand on this further? --Xanthine 18:22, 1 September 2006 (UTC)

Weak acid?
am doing a report for uni is sulfamic acid a weak acid?

Unreliable/ambiguous picture?
This may seem pedantic, but the picture showing the normal (unionized) structure and zwitterionic structure may be confusing to some, as they may see it as one whole structure, so I propose it would be better to add a double arrow (equilibrium like) to show that the acid can exist in both of these forms. Anyone agree or am I being silly? --Mark PEA 19:12, 16 June 2007 (UTC)
 * Yes, you make a good point. It could use a pair of equilibrium arrows.--Smokefoot 20:51, 16 June 2007 (UTC)

Perhaps update phrase for clarity?
IMHO, perhaps this sentence could be clearer?

" From all acid, Sulfamic acid has the best water descaling property, thus also its application in cleaning dairy farm equipment and beer brewery."

Perhaps

"Sulfamic acid is among the best acids for removing water scale, so it is often used to clean dairy farm and beer brewing equipment."

(I am putting this a suggestion, because I do not have the technical knowledge to know that it is the 'best'.) —Preceding unsigned comment added by 198.145.78.198 (talk) 20:18, 17 December 2008 (UTC)

CLR cleaner
sulfamic acid is the ingredient in CLR cleaner along with citric acid. —Preceding unsigned comment added by Ericg33 (talk • contribs) 00:40, 28 August 2009 (UTC)

Solubility
The information about solubility is not clear. In The first paragraph it says: water soluble. On the side column it says: moderately soluble. I am not sure if this is a scientific term. Solubilities are found in the safety data sheets easily. In the German wikipedia it is "leicht löslich" which translates to "freely soluble" (213 g·l−1 at 20 °C). 79.215.114.216 (talk) 08:18, 24 August 2020 (UTC)

Sulfamic acid reacting with ternary/oxidizer acids hypothesis
Hello.

The article cites that sulfamic acid reacts with nitrous and nitric acid thru the following reaction (respectively):

H3NSO3 + HNO2 → H2SO4 + N2

H3NSO3 + HNO3 → H2SO4 + N2O

Could this not be applied to other reactions with ternary acids, such as Iodic acid or Hypochloric acid in one of those various ways? :

10 H3NSO3 + 6 HIO3 = 10 H2SO4 + 8 H2O + 5 N2 + 3 I2

Here, diiodide is (mostly) insoluble in a water medium, and therefor could precipitate. The presence of unreacted products could however contribute to it dissolving.

2H3NSO3 + 6 HClO = 2 H2SO4 + 4 H2O + 3 Cl2 + N2

I might add enthalpy to those in a later reply.

Aqueous solutions of sulfamic acid are only unstable at elevated temperatures
Sulfamic acid does undergo hydrolysis, but the rate is very slow at room temperature. .Ahelto14 (talk) 15:23, 10 March 2021 (UTC)
