When the unit amount of the flux factor represents the metal or sulfur oxide, a certain desired amount of the oxidizing agent. Different metals and different oxidants have different flux coefficients. Flux coefficient and oxygen coefficient of various substances Substance name Atomic quantity or number of moles Oxide Oxygen coefficient Flux coefficient Acidic Alkaline NaNO 3 MnO 2 Cu (- price) 63 Cu 2 O 　 0.127 0.46 0.7 Zn 65 ZnO 　 0.246 0.87 1.35 Pb 207 PbO 　 0.077 0.28 0.43 Fe 56 FeO 　 0.285 1.01 1.57 S 32 SO 3 　 　 5.3 8.3 CaO 56 CaO 　 0.285 　 　 NaNO 3 85 Na 2 O 　 0.094 　 　 MnO 2 87 MnO 　 0.184 　 　 Na 2 CO 3 100 Na 2 O 　 0.151 　 　 Na 2 O 62 Na 2 O 　 0.258 　 　 SiO 2 60 SiO 2 0.534 　 　 　 Na 2 B 4 O 7 202 2B 2 O 3 · Na 2 O 0.477 0.079 　 　 Chevy Gm Parts,Gm Chevy Small Block,Chevy Manifold Exhaust Pipe,Gm Manifold Exhaust Pipe Ningbo Lingmai Machinery Manufacturing Co., Ltd. , https://www.lingmaimfg.com
The flux coefficients of sulfur and saltpeter are:
S + 2NaNO 3 = Na 2 O + 2NO + SO 3
32 2×85
170
Therefore, the sulfur nitrate flux coefficient is ——= 5.3. That is, it is necessary to oxidize a unit amount of sulfuric acid by 5.3 units of nitrate.
