an ore of zinc on treatment with dilute hydrochloric acid releases brisk effervescence of a colourless and odourless gas identify the type of ore and the method that may be used to get the oxide of metal from the ore and also suggest a method to extract the metal from the oxide write all equations involved |

Answer» The TYPE of ore is, carbonate ore. The operation required to obtained metal from it will be, calcination process. Explanation : When an ore on the TREATMENT with the dilute hydrochloric acid produces brisk effervescence to produce a colorless and ODORLESS gas then the ore should be carbonate ore. The operation required to obtained metal from it will be, calcination process. Calcination process : When the metal carbonate on treatment with the dilute hydrochloric acid, it releases carbon dioxide as a colorless and odorless gas with brisk effervescence. Hence, by the calcination process the metal carbonate ore are converted to their metal oxides. The reactions involved are : (1) The metal carbonate ore on heating gives metal OXIDE and carbon dioxide. (2) The reduction of metal oxide with the carbon to give metal and carbon monoxide as a gas. |
