Question 1.Why should a magnesium ribbon be cleaned before burning in air ?

Answer: Magnesium ribbon should be cleaned with sand paper before burning in air order to remove white layer of magnesium oxide (MgO) from its surface which hinders the burning of magnesium.

Question 2.Write the balanced equation for the following chemical reactions.

i) Hydrogen + Chlorine → Hydrogen chloride

ii) Barium chloride + Aluminium sulphate → Barium sulphate + Aluminium chloride

iii) Sodium + Water → Sodium hydroxide + Hydrogen

Answer:

i) H2(g) + Cl2(g) → 2HCl2(g)

ii) 3BaCl2(aq) + Al2(SO4)3(aq) → 3BaSO4(s) + 2AlCl3(aq)

iii) 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)

Question 3.Write a balanced chemical equation with state symbols for the following reactions.

i) Solutions of barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride.

ii) Sodium hydroxide solution (in water) reacts with hydrochloric acid solution (in water) to produce sodium chloride solution and water.

Answer:

i) BaCl2(aq) + Na2SO4(aq) → BaSO4(s) + 2NaCl(aq)

ii) NaOH(aq) + HCl(aq) → NaCl(aq) + H2O (l)

Question 4.A solution of a substance ‘X’ is used for white washing.

i) Name the substance ‘X’ and write its formula.

ii) Write the reaction of the substance ‘X’ named in (i) above with water.

Answer:

i) For white washing a solution quick lime is used. The substance ‘X’ is quick lime and its formula is CaO (Calcium oxide)

ii) When quick-lime reacts with water, the following reactions takes place.

Question 5. Why is the amount of gas collected in one of the test tubes in Activity 1.7 double of the amount collected in the other ? Name this gas.

Answer:

During electrolysis, water decomposes to form hydrogen and oxygen gases.

In the above reaction, the balanced chemical equation shows that an electrolysis, the water decomposes to form hydrogen and oxygen in the ratio of 2 : 1 by volume.

Question 6.Why does the colour of copper sulphate solution change when an iron nail is dipped in it ?

Answer:

Iron is more reactive element than copper. When an iron nail is dipped in copper sulphate solution which is blue in colour, iron being more reactive than copper displaces copper from copper sulphate and forms, iron (II) sulphate which is green in colour.

Question 7.Give an example of a double displacement reaction other than the one given in Activity 1.10.

Answer:

AgNO3 (aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)

Question 8.Identify the substances that are oxidised and the substances that are reduced in the following reactions.

i) 4Na(s) + O2(g) → 2Na2O(s)

ii) CuO(s) + H2(g) → Cu(s) + H2O(I)

Answer:

i) Na has gained oxygen and forms Na20. So, Na is oxidised and O2 is reduced.

ii) CuO has lost oxygen and forms Cu. So, CuO is reduced and H2 which has gained oxygen is oxidised.

Question 7.

plain electrolysis of water with an activity (or) With the help of an activity explain that H2 and O2 are released when an electric current is passed through vater.

Answer:

Aim : 

To demonstrate electrolysis of water.

Materials required : 

Plastic mug, drilling machine, two graduated measuring cylinder, carbon electrodes, 6 volt battery, dil H2SO4, Water.

Procedure :

Take a plastic mug. Drill two holes at its base and fit rubber stoppers in these holes. Insert carbon electrodes in these rubber stoppers as shown in figure.

Connect these electrodes to a 6-volt battery.

Fill the mug with water such that the electrodes are immersed. Add a few drops of dilute sulphuric acid to the water.

Take two test tubes filled with water and invert them over the two carbon electrodes.

Switch on the current and leave the apparatus undisturbed for some time.

You will observe the formation of bubbles at both the electrodes. These bubbles displace water in the test tubes.

Observe the volume of gases collected in respective test tubes.

Once the test tubes are filled with the respective gases, remove them carefully.

Test these gases one by one by bringing a burning candle close to the mouth of the test tubes.

Observation : 

The volume of one gases, i.e., hydrogen is twice the volume of other gas. One of the gases catches fire and burns with ‘pop’ sound where as in other gas, e.g. oxygen, match-stick burns brightly.

Conclusion : 

Water on electrolysis decomposes to hydrogen and oxygen gas.

Activity – 1.8 (Page. No. 20)

Question 8.
