此反应的平衡化学方程式如下: SO3 + Ca(OH)2 —》 CASO4 + H2O。 。 由于这种反应,不溶的硫酸钙以白色固体的形式沉淀。 这种化学过程的特点是产物硫酸钙的不溶性,以及水作为副产物的产生。 This reaction is a classic example of what happens when an acid (SO3) and a base (Ca(OH)2) mix ...
This marked difference is due to SO3 being a much stronger Lewis acid (pF(-) value of 7.83) than SO2 (pF(-) value of 3.99), thus forming a stronger S-N bond with the Lewis base N-3(-). The geometry of the free gaseous SO2N3- anion was calculated at the RHF, MP2, B3LYP, ...

As a consequence, the Lewis acid–base interaction could readily take place thus enhancing the mobility of ions and increasing the ionic conductivity. When ultrasonic stirring was applied for 30 and 60 min, the ionic conductivity was reduced by about one order of magnitude (Table 3). This ...

The flue gas desulfurization (FGD) process is based on complex acid-base reactions that take place under forced or natural oxidation conditions. In both cases, SO2 in flue gas reacts with CaCO3 provided in the FGD slurry to produce CaSO3∙2H2O, which can be converted to CaSO4∙2H2O or...
