Answers


Yegon
Green solid is Copper(ii)Carbonate
When added to dilute nitric acid it reacts to form copper(ii) nitrate(blue) and carbon (iv) oxide and water which is blue in colour more addition of acid results in a deep blue complex copper ion
Cations- positively charged ions in a compound
Anions- negatively charged ions in a compound
Compound- in this case is Copper (ii) carbonate(CuCO3) Has two parts Cu+(cation) and a radical CO3^2-(anion)
