How will the color of the solution change? Suppose heat is added to the reaction mixture. b. i. If the reaction mixture turns pink, then it is an (exothermic/endothermic) reaction. ii. If the reaction mixture turms blue, then it is an (exothermic/endothermic?) reaction. 162

need help with 6a and 6b

Answer 1

6a) I) Cl^- ion is added.

II) Reaction shift towards reactants as per the Lechatelier's principle to decrease the concentration of Cl-.

III) Color change to blue.

b) I) Endothermic. Because adding heat shift equilibrium towards product which happens in Endothermic reaction.

II) Exothermic. Because adding heat shift the equilibrium towards product which happens in Exothermic reaction.
