Nitrous Acid.
Experiment 140. —Melt 25 grams potassium nitrate in a shal- low iron plate and gradually add 50 grams metallic lead cut in small pieces. Stir them together as thoroughly as possible. After the mass is cooled down, break it up and treat with water in a flask. The potassium nitrate will dissolve, while the lead oxide and unused lead will not dissolve. Filter. Add a little, sulphuric... acid to some of the solution. A colored gas will be given off. See whether a solution of potassium nitrate acts in the same way.
Treat with sulphuric acid a little of the residue left after heating potassium nitrate alone in a test-tube as in Experiment 138.
Nitrous Oxide.
1 Experiment 141.— In a retort heat 10 to. 15 grams crystallized ammonium nitrate until it has the appearance of boiling. Do not heat higher than is necessary to secure a regular evolution of gas. Connect a wide rubber tube directly with the neck of the retort and collect the evolved gas over water, as in the case of oxygen.
