Acido arsenioso - Wikipedi

L' acido arsenioso è un composto inorganico con formula H 3 AsO 3. Il composto è noto per formarsi in soluzione acquosa, ma non è mai stato isolato come materiale puro, sebbene questo fatto non tolga significato alla formula As (OH) 3 L' acido arsenico è un composto chimico con formula bruta H 3 AsO 4, scritta anche come AsO (OH) 3. Il composto, incolore, è analogo all' acido fosforico. I due acidi, così come i rispettivi sali, si comportano in modo simile. L'acido arsenico non è mai stato isolato come tale, se non in soluzioni in cui si trovava completamente dissociato Ispirato da this question, mi chiedo perché l'acido arsenous sia spesso indicato $$\ce {H3AsO3} $, al contrario di $$\ce {As (OH) 3} $, che sembrerebbe riflettere più accuratamente la sua connettività? [modificare] Mi sento un tale dozzina, dimenticando $$\ce {H2SO4} $, $$\ce {H3PO4} $, ecc. Ottima discussione, gente H3AsO3 + H2O → H3AsO4 + 2H + + 2e- (ξ0 = -0,560 V) L'acido arsenico è un agente ossidante più forte della sua controparte fosfonica, ma un agente riducente più debole di questo (Egon Wiberg, 2001). Reattività e rischi. L'acido arsenico è un composto classificato come stabile, tuttavia è un reagente tossico e corrosivo

In modo analogo, determiniamo la massa molare di NaCl. Mm (NaCl) = 23 + 35,45 = 58,45 g/mol. E' possibile determinare a questo punto la quantità chimica di CaCl 2 dividendo la massa in grammi per il valore della massa molare:. n (CaCl 2) = g / Mm = 150 / 110,98 = 1,35 mol.
