Now what if one shifts the equilibrium of just sulfamic acid from NH3SO3 to NH2SO3. Charge changes. I think it may also read on strips.If one made a solution containing ammonium sulfamate (meaning there is ammonia and ammonium and sulfamate in solution) , it will show in a test just the same as ammonium chloride solution or household ammonia (ammonium hydroxide) unless the sulfamate itself messed up the test chemistry somehow (which is unrelated to whether the ammonia/ammonia is detectable).
