write description of calcium ion, copper ion, iron ion and the picture
Answers
Answer:
Calcium Ion :-
Calcium Ion :- A few drops of dilute sodium hydroxide solution react to form a white precipitate with aluminium ions and with calcium ions. However, if excess sodium hydroxide solution is added: the aluminium hydroxide precipitate reacts to form a colourless solution. the calcium hydroxide precipitate is unchanged.

Aqueous copper(II) ions, [Cu(H2O)62+], will give the solution a pale blue hue. When the solution is colorless it is presumed to no longer have copper ions dissolved in it.

Non-haem iron in food is mainly in the ferric state, which is the insoluble form of iron, and must be reduced to the ferrous cation for absorption.
