Please find the complete question in the attached file.
Explanation:
Answer : The question is incomplete and the complete question is attached in the answer;
Answer 1) When HCl was added to the system of cobalt chloride it will eventually produce more Cl ions in the solutions which will shift the equilibrium to the right and make the solution look more blue than before. To accommodate extra Cl ions in the system the equilibrium gets shifted.
Answer 2) When in the reaction system water is added the Cobalt chloride compound forms a hydrated mixture; this means the equilibrium reaction shifts to the left and produces more hydrated ions along with more chlorine ions in the solution.
Which then turns the resultant solution tinto pink in colour.
Solution
Given mass of FeBr2 = 85.5 g
Molar mass of FeBr2 = 215.65
No. of Moles of FeBr2 = Given Mass / Molar mass = 85.5 / 215.65
No. of Moles = 0.3964
Given Volume is 450 mL i.e. 0.450 L
Now Concentration = 0.3964/0.450
Hence Concentration = 0.881 mol/L
