Around one third of all sulphuric acid production comes as a by-product from smelting of primary metals, especially copper. With regulations on emissions of SO2 from smelters continuing to tighten around the world, this means that almost any new smelting capacity will generate more acid. On the...

The sample was finally treated with concentrated sulphuric acid by shaking in a separating funnel to remove interferences. The hexane supernatant was concentrated and cleaned up with a multi-layer silica-gel column, eluted with 200 mL hexane. The sample was further fractionated using a silica-...
The electroplating bath, SS303 (0.48 mol L-1CuSO4·5H2O, 1.90 mol L−1sulphuric acid, 52 ppm chloride ion, and several additives), supplied by Doctech Ltd. (Hong Kong, China), was used to fabricate different kinds of Cu films via direct current (DC) electroplating. By tu...
But as you can see, a weak acid (acetic acid) is displacing a stronger acid (sulphuric acid) from its salt. That's not possible.On the other hand, when you add NaOH, the acid being displaced is H2O, which is certainly weaker than acetic acid. (wirte the equation)P.S : I recently...
