Zinc being more reactive than hydrogen, displaces it from sulphuric acid. When zinc reacts with dilute sulphuric acid hydrogen gas is evolved, with an effervescence. ... When dilute sulphric acid reacts with zinc granules, thenzinc sulphate and hydrogen gasare formed. (i) ZnS + H2SO4 →...
Effect of temperature was studied at 30, 45 and 60°C. The effect of the number of extraction and stripping stages and the volume phase ratios in extraction and stripping upon sulphuric acid recovery is discussed. 展开 关键词:Solvent extraction TEHA Zinc bleed stream Extraction ...

The material is leached with sulphuric acid to produce a final pH of 3-5.5. Zinc powder is added to the leaching solution to precipitate polluting metals. Zinc is now extracted with a solution of a dialkyl phosphoric acid in an organic solvent. Zinc is extracted from the organic solution ...
Give an equation in each case. View Solution Hydrogen can be prepared with the metal zinc by using : water Give an equation in each case. View Solution Why is sulphuric acid used in the preparation of HCI andHNO3? Give equations in both cases. ...
What happens when concentrated sulphuric acid is added to hydrated copper (II) crystals? Is copper (II) nitrate an acid or a base? What is the net ionic equation and the ionic equation for HCLO4(aq)+Mg(OH2(s)? Bases produce which ions in aqueous solution?
