(a) State what would be observed when:

(i) Chlorine is passed through a freshly prepared solution of FeCl\(_2\).

(ii) SO\(_2\) is bubbled into a solution of FeCl\(_3\);

(iii) A few drops of water Is added to sodium hydroxide pellets in a test tube;

(iv) Dilute H\(_2\)SO\(_4\) is added to CaCO\(_{3(s)}\)

 

(b) Three test tubes contain solutions of SO\(_3^{2-}\), CO\(^{2-}_3\) and SO\(_4^{2-}\) respectively. Describe one chemical method that you would use to identify the solution containing SO\(_4^{2-}\) 

 

(c)(i) Draw and label a diagram to illustrate the separation of a mixture of petrol and water

(ii) Which of the following will dissolve faster? 10g of NaOH pellets in 100 cm\(^3\) of water; 10g of NaOH powder in 50 cm\(^3\) of water. Give the reason for your answer.
