Give a balanced chemical equation for Laboratory preparation of Nitric acid.
Complete and balance the following equation :
C + HNO3 → ___________
Give reason for the following:
In the laboratory preparation of nitric acid, the mixture of concentrated sulphuric acid and sodium nitatre should not be heated very strongly, above 200°C
Write a balanced equation for the production of nitrogen dioxide using copper.
During a thunderstorm, the rainwater contains nitric acid. The nitric acid is formed as a result of three chemical reactions. Describe or write balanced chemical equation for these three reactions.
Why does pure nitric acid take on a yellowish brown colour when exposed to light?
Dilute nitric acid is generally considered to be a typical acid except for its reaction with metals. In what way is dilute nitric acid different from other acids when it reacts with metals?
What is the special feature of the apparatus that is used in the laboratory preparation of nitric acid?
Balanced equation of oxidation of carbon with concentrated HNO3
X, Y, and Z are three crystalline solids that are soluble in water and have common anion.
To help you to identify X, Y and Z, you are provided with the following experimental observations. Copy and complete the corresponding inferences in (a) to (e).
- A reddish-brown gas is obtained when X, Y, and Z are separately warmed with concentrated sulphuric acid and copper turning added to the mixture.
INFERENCE 1: The common anion is the ______ ion. - When X is heated, it melts and gives off only one gas which re-lights a glowing splint.
INFERENCE 2: The cation in X is either ______ or ______. - The action of heat on Y produces a reddish-brown gas and yellow residue which fuses with a glass of the test tube.
INFERENCE 3: The metal ion present in Y is the ______ ion. - When Z is heated, it leaves no residue. Warming Z with sodium hydroxide solution liberates a gas which turns moist red litmus paper blue.
INFERENCE 4: Z contains the ______ cation. - Write the equations for the following reactions:
- X and concentrated sulphuric acid (below 200°C). (One equation only for either of the cations given in INFERENCE 2)
- The action of heat on Y.
- Concentrated nitric acid is added to copper turnings kept in a beaker.
