(v) What is the nature of zinc oxide ?
(vi) Will carbon monoxide (CO) change the colour of blue litmus?
Answers
ANS. (1) copper
ANS. (2) Graphite
ANS. (3) aluminium
ANS. (4) The impure metal is made anode (positive terminal) and a thin rod of pure metal is made cathode (negative terminal). ... When electricity passed through the cell, the impure metal dissolves in the electrolytic solution. The pure metal from the electrolytic solutions moves and gets deposited at the cathode.
ANS. (5) Zinc oxide is an inorganic compound with the formula ZnO. It is a white powder that is insoluble in water.
ANS.(6) It will change colour if the litmus paper is moist. In the normal scenario,the carbon monoxide will not change the colour of the blue litmus.Due to the acidity of the generated carbonic acid,the litmus paper turns red.
