Give a balanced chemical equation for Laboratory preparation of Nitric acid.
The action of heat on the blue crystalline solid X gives a reddish brown gas Y, a gas which re-lights a glowing splint and leaves a black residue. When gas Z, which has a rotten egg smell, is passed through a solution of X, a black ppt. is formed.
- Identify X, Y and Z.
- Write the equation for action of heat on X.
- Write the equation between solution X and gas Z.
Complete and balance the following equation :
Fe + HNO3(conc.) → _____________
Fill in the blank with appropriate word/words.
Ammonal is a mixture of ________ and __________
The first step in the manufacture of nitric acid is the catalytic oxidation of ammonia. What is the name of the catalyst?
Explain the following :
An all glass apparatus is used in the laboratory preparation of nitric acid.
Write a balanced equation for following :
Reaction of ammonia with nitric acid
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.
Explain why only all-glass apparatus should be used for the preparation of nitric acid by heating concentrated sulphuric acid and potassium nitrate.
The figure given below illustrates the apparatus used in the laboratory preparation of nitric acid.
- Name A (a liquid), B (a solid), and C (a liquid). (Do not give the formulae).
- Write an equation to show how nitric acid undergoes decomposition.
- Write the equation for the reaction in which copper is oxidised by concentrated nitric acid.
