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
Answers
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.
