Question

Write chemical formulae of all the compounds that can be formed by the combination of following ions : Ca^2-, Fe^3-, K-, Cl^2, SO^2- and 4

Answer 1

Hey Friend,

The cations are Ca ++ , Fe +++ , K + 
The anions are Cl - , SO2 -- , SO4 --

So, following compounds can be made from the given cations and anions,

CaSO4 (calcium sulphate)

CaSO2 (calcium hyposulphite)

CaCl2 (calcium chloride)

FeCl3 (ferric chloride)

Fe2(SO4)3 (ferric sulphate)

Fe2(SO2)3 (ferric hyposulphite)

KCl (potassium chloride)

K2SO4 (potassium sulphate)

K2SO2 (potassium hyposulphite)

Hope it helps!

Answer 2

Answer:

The chemical formulae of all the compounds that can be formed by the combination of the following ions: $Ca^2-, Fe^3-, K-, Cl^2, SO^2$ are as follows.

Explanation:

Cations exist as positively-charged ions (atoms or groups of atoms that contain more additional protons than electrons due to having lost one or more electrons). Anions exist as negatively-charged ions (indicating they contain more electrons than protons due to having gained one or more electrons).

The cations are $Ca ++ , Fe +++ , K +$

The anions are $Cl - , SO2 -- , SO4 --$

So, the following compounds can be made from the given cations and anions,

• $CaSO_{4}$ (calcium sulphate)

• $CaSO_{2}$ (calcium hyposulphite)

• $CaCl_{2}$ (calcium chloride)

• $FeCl_{3}$ (ferric chloride)

• $Fe_{2} (SO_{4} )_{3}$ (ferric sulphate)

• $Fe_{2} (SO_{2} )_{3}$ (ferric hyposulphite)

• $KCl$(potassium chloride)

• $K_{2} SO_{4}$ (potassium sulphate)

• $K_{2} SO_{2}$ (potassium hyposulphite)
