Very Short Ans Questions on Nitric Acid
Page-175
Que-1: Name:
(a) A nitrate of metal which on heating does not give nitrogen dioxide.
(b) A nitrate which on heating leaves no residue behind.
(c) A metal nitrate which on heating is changed into metal oxide.
(d) A metal nitrate which on heating is changed into metal.
(e) A solution which absorbs nitric oxide.
(f) The oxide of nitrogen which turns brown on exposure to air. How is it prepared?
(g) the gas produced when copper reacts with conc. HNO3.
Ans:
(a) Sodium nitrate: 2NaNO3 → 2NaNO2 +O2
(b) A nitrate which on heating leaves no residue behind- Ammonium nitrate.
(c) A metal nitrate which on heating is changed into metal oxide- Calcium nitrate
(d) A metal nitrate which on heating is changed into metal- Silver nitrate
(e) A solution which absorbs nitric oxide- Freshly prepared ferrous sulphate
(f) The oxide of nitrogen which turns brown on exposure to air. – nitric oxide
By catalytic oxidation of ammonia.
4 NH3 + 5 O2 (pt) → (800ºC) 4NO + 6 H2O + Heat
(g) Nitrogen dioxide: Cu + 4HNO3 → Cu(NO3)2 + 2H2O + 2NO2
Que-2: Identify the gas evolved when:
(i) Sulphur is treated with conc. nitric acid.
(ii) A few crystals of KNO3 are heated in a hard glass test tube.
Ans:
(i) When sulphur is treated with conc. nitric acid, it produces nitrogen dioxide gas.
(ii) When a few crystals of KNO3 are heated in a hard glass test tube, it decomposes to form KNO2, and O2 gas is librated.
Que-3: Identify the acid:
(i) The acid which is used in the preparation of a non-volatile acid.
(ii) The acid which is prepared by catalytic oxidation of ammonia.
Ans:
(i) Sulphuric acid
(ii) Nitric acid
Que-4: From the following list of substances, choose one substance in each case which matches the description given below:
Ammonium nitrate, Calcium hydrogen carbonate, copper carbonate, lead nitrate, potassium nitrate, sodium carbonate, sodium hydrogen carbonate, zinc carbonate.
(a) a substance which gives off only oxygen when heated.
(b) A substance which on heating decomposes into dinitrogen oxide (nitrous oxide) and steam.
(c) A substance which gives off oxygen and nitrogen dioxide when heated.
(d) A substance which on heating leaves yellow residue.
Ans:
(a) Potassium nitrate
(b) Ammonium nitrate
(c) Lead nitrate
(d) Lead nitrate
Que-5: Complete the table:
| Name of Process | Inputs | Equation | Output |
| Ammonia + Air | Nitric acid |
Ans:
| Name of Process | Inputs | Equations | Output |
| Ostwald process | Ammonia + Air | 4NH3 + 5O2(Pt) → (700−800°C) 4NO + 6H2O + 21.5K cals | Nitric acid |
