Na+ and Cl- are spectator ions.
Zn(s) → Zn2+(aq) + 2e- and Fe3+(aq) + e- → Fe2+(aq)
Hydrochloric acid and sodium hydroxide yield salt and water H+ + Cl- + Na+ + OH- --> Na+ + Cl- + H2OComment:In solutions you better leave unchanged ions ( Cl- and Na+) out of the balanced equation: called to be 'tribune ions' (people on the tribune don't take part in the 'match'):H+ + OH- --> H2O This looks simpler than: H+ + Cl - + Na + + OH- --> Na + + Cl - + H2O
since the powers 3+ = 3- the cancel each other out so the formula becomes FeN hope this helped.
Calcium Chloride
The chemical equation is:3 AgNO3 + FeCl3 = 3 AgCl + Fe(NO3)33 Ag + 3 NO3- + Fe3+ + 3 Cl- = 3 AgCl(s) + 3 NO3- + Fe3+
Na+ and Cl- are spectator ions.
b. Fe3 plus ions
To separate Fe3+ ions, one can use a reagent like ammonia (NH3) which forms a complex with Fe3+ ions called iron(III) hydroxide. This complex precipitates out of the solution, allowing for the separation of Fe3+ ions from other components in the mixture.
The solution of FeCl3 is acidic. This is because when FeCl3 dissolves in water, it forms Fe3+ ions and Cl- ions. The Fe3+ ions react with water to produce H+ ions, which makes the solution acidic.
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.
Zn(s) → Zn2+(aq) + 2e- and Fe3+(aq) + e- → Fe2+(aq)
No, it doesnot as Potassium has only one positive charge.
Here is a covalent bond.

Potassium thiocyanate can be used to confirm the oxidation of Fe2+ ions to Fe3+ ions by forming a blood-red complex with Fe3+, known as iron(III) thiocyanate. Upon the addition of potassium thiocyanate, if a blood-red color formation is observed, it indicates the presence of Fe3+ ions, confirming the oxidation of Fe2+ ions.
The net ionic equation for the given reaction is H+ (aq) + OH- (aq) → H2O (l)
