Question
d) In 4 test tubes, divide equally the solution prepared in procedure c into four parts. Reserve the first test tube as a standard. 1) To the second test tube add 1 mL of ferric chloride solution. 2) To the third test tube add 1 mL of ammonium thiocyanate solution. 3) To the fourth test tube add a pack of solid ammonium chloride. Compare the color obtained in test tubes 2,3,4 with the first test tube(standard solution). Record and explain your observations. Was the reaction in procedure c complete? Can the reaction be made reversible? Define common ion effect. 2. a) Heat a pack of sawdust in a stained test tube. Observations. Is the reaction reversible or irreversible? Complete or incomplete? b) Recall the reactions of: i. Magnesium ribbon (ignited) and oxygen; ii. potassium chlorate and heat; iii. blue vitriol and heat. Write the chemical equations for each of the above reactions and classify each as reversible or irreversible and complete or incomplete?
