NITRIC ACID PRODUCTION Nitric acid is almost always made by mixing gaseous ammonia with air, converting it to nitric oxide (NO) in a reactor over a platinum-rhodium catalyst at 800950 C (14701740 F), and further oxidizing the NO to NO 2. For the small scale preparation, nitric acid is made when concentrated sulphuric acid is heated along with NaNO3 or KNO3.

So to prepare 2% nitric acid you could take say 20 grams of this, Results showed The nitric acid is produced by a series of oxidation steps starting from oxidation of ammonia. The other raw materials are water and a source of oxygen, commonly air is used. There are three primary chemical reaction steps in the Ostwald Process: Catalytic oxidation of ammonia to yield nitrogen monoxide. The apparatus used for the preparation of Nitric acid must be made of glass. There are three primary chemical reaction steps in the Ostwald Process:Catalytic oxidation of ammonia to yield nitrogen monoxide.Oxidation of nitrogen monoxide to yield oxides of nitrogen.Absorption of oxides of nitrogen in water to yield nitric acid. 2. Watch all CBSE Class 5 to 12 Video Lectures here. 3.3 Transfer slowly, through sidewalls of the beaker, 53.0 ml of Nitric Acid LR (about 10ml on each attempt) into above said beaker, while gentle mixing, by using a glass rod. 1. 3.2 Pour about 75.0 ml of distilled water into a 250 ml capacity beaker. Potassium nitrate [nitre] KNO 3 + H 2 SO 4 [conc.] Nitric acid is a strong mineral acid. In the nitric acid treatment process, when the nitric acid concentration was low (10 wt% or less), the prepared activated carbon showed low specific surface areas of Some important uses of nitric acid are: 1. Q. Nitric acid. Preparation of Nitric Acid: In the laboratory, nitric acid is prepared by heating a mixture of sodium or potassium nitrate and concentrated sulfuric acid. 3.2 Pour about 75.0 ml of distilled water into a 250 ml capacity beaker. 3 mins read. Nitric acid is the inorganic compound with the formula H N O 3. (c) Conc. NITRIC ACID ( HNO3) INTRODUCTION . PREPARATION. 2.1 Nitric Acid. Laboratory preparation 3.3 Transfer Sulfuric acid is more dangerous acid than nitric acid. Sulfuric acid has two full positive charges on sulfur. This has the effect of pulling electrons from the attached oxygen atoms which increases the apparent electronegativity of the oxygen atoms. The density of 70% (w/w)Nitric acid is 1.413 g/ml at 25C which means that the weight of the 1 ml of Nitric acid is 1.413 gram at 25C. Patient Math & Science Tutor. It is a mono-basic acid. 3.2 Pour about 200 ml of distilled water It usually gets oxidized again by the oxygen present in the air. It is a strong oxidizing agent and can oxidize metals and nonmetals easily. 3.1 Measure 53.0 ml of Nitric Acid LR and transfer into a 100 ml capacity beaker. It is a highly corrosive mineral acid. Nitric acid dissolves copper and silver by oxidizing them, as described by the chemical equations below. The more copper or silver within the gold alloy, the faster the alloy will dissolve. What metal does not react with hydrochloric acid? Answer: The most common commercially available nitric acid for laboratory use is about 67% nitric acid by weight. Preparation of Nitric Acid. nitric acid prepared in laboratory is yellow in colour. 3.3 Transfer slowly, through sidewalls of the beaker, 10.6 ml of Nitric Acid LR into above said beaker, while gentle mixing, by using a glass rod.
