Abstract
Dependence of sulfamic acid salts solvability in water - С S (in gr of salt/100 gr Н 2 O) with the general chemical formula Ме(SO 3 NH 2 ) n , where, Mе + n is one-, two- and three-charge cations of metal, and - n is value of charge, was researched. Also specific aspects of distribution of salts Ме(SO 3 NH 2 ) n according to calculated size of Gibbs free energy – ∆G S , from the radius length – r +n (in nm) of sulfamate formative metal cation were examined. Using graphic methods and methods of mathematical analysis of the functions С S = f (r +n ) and ∆G S = f (r +n ) correlation of special points of these functions with fundamental physical and chemical constants was found. It was calculated the size of sulfamate-ions radius with cvitter-ion ( r -і ) + H 2 NSO 3 - = 254,932 ± 0,001 pm, and with open ( r - і ) NH 2 SO 3 - = 255,96 5 ± 0,0 0 5 pm structure. Also estimated values of С S for sulfamates formed by two- and three-charge cations of Vanadium, Manganese and Chromium were clarified.
