Sodium nitrate
Name the catalyst used in Ostwald process.
Explain with the help of a balanced equation, the brown ring test for nitric acid.
Give reason for the following:
Lighting is a blessing in disguise.
What happen when (Given balanced equation):
Nitric acid is added to washing soda and the resulting gas is passed through a freshly prepared lime water?
Give two chemical tests to distinguish between dilute nitric acid and hydrochloric acid.
Fill in the blank with appropriate word/words.
Ammonal is a mixture of ________ and __________
Complete and balance the following equation:
Cu + HNO3 → NO2 + ________+ _________
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.
