Explanation / Answer

Question 4: KCl is an aqueous solution.

FeF3 is solid dissolved in the KCl solutiojn.

Question 5: FeF3 is alewis acid. So to find out if the reaction has occured we have to use Methyl orange indicator. Methyl orange shows red colour in acidic medium. It's Ph range is 3.1 - 4.4.
