Answer 5

Orange

Question 6

Solution of I in cyclohexane, what is the colour of the top layer of the solution

Answer 6

Violet

Question 7

Cl2 (aq) in Br- (aq) solution

colour change

Answer 7

Plae green to Orange colour, because of Br2 formation

Cl2 (aq) + 2Br- (aq) —> 2Cl- (aq) + Br2 (aq)

Question 8

Cl2 (aq) in I- (aq) solution

Answer 8

Pale green to violet colour, because of I2 formation

Cl2(aq) + 2I- (aq) —> 2Cl- (aq) + I2 (aq)

Question 9

Answer 9

no reaction

Question 10

Br2 (aq) in I- (aq) solution

Answer 10

orange to violet colour, because of I2 formation

Br2 (aq) + 2I- (aq) —> 2Br- (aq) + I2 (aq)

Question 11
