Oxygen gas has an oxidizing strength comparable to that of nitric acid. Patina is a green or greenish-blue coating that forms on copper metal in the environment. Account for its formation. 3. Test tube 7. Does the ferrous ion in the Fe(NH_4_)_2(SO_4)_2 solutions function as an oxidizing agent or a reducing agent? Explain. Test lube 8. a. What was the color change of the I^- in the reaction? b. Does the I^- solution function as an oxidizing agent or a reducing agent? Explain. 1. Eliseo couldn't find the 6 M HCl and so used 6 M HNO_+3 for testing the metals instead. His logic? Both are strong acids. Explain how the results of the experiment would have been different. Single displacement, double displacement, and decomposition reactions may all be redox reactions. Identity the type of redox reactions in Part C. Explain. a. On the basis of your intuitive understanding of the chemical properties of sodium and gold, where in your activity series would you place sodium and gold? b. Will hydrochloric acid react with gold metal to produce gold(III) ions and hydrogen gas? Explain.

Explanation / Answer

1) Sodium metal is readily oxidised by oxygen .the reaction can be shown as:-

2 Na + O2  -----------> Na2O

The product of the reaction is dissolved in water.So, it reacts with water to form sodium hydroxide.

Na2O + H2O --------------> 2NaOH

so the solution becomes basic in nature .The colour of litmus will be blue.
