Question

chemical reaction of non metals with copper sulphate solution​

Answer 1

Answer:

Chemical Properties of Metals

The chemical properties of metals are –

Oxidation

All metals except the noble metals, which is gold and silver react with the oxygen to form basic oxides. In the reaction, the Sodium reacts vigorously with oxygen and generates a lot of heat. For example –

Magnesium (Mg) + Oxygen (O2)  —- 2MgO (Magnesium Oxide)

Rusting of Iron

Iron (Fe) + Oxygen (O2) + Water (H2O) ——— Fe2O3 (Iron Oxide, is a brown color rust)

Greenish Deposit on the Surface of Copper Vessels

The dull greenish material that is deposited on the surface of copper is a mixture of copper hydro oxide [Cu(OH)2] and copper carbonate (CUCO3) which takes place as –

2Cu + H2O + CO2 + O2 ——- [Cu(OH)2] + (CUCO3)

Reaction of Metals with Water

The metallic oxides are basic in nature. Metals like sodium (Na) react vigorously with water at room temperature.

2Na + 2H2O ——— 2NaOH + H2 (Hydrogen hydroxide)

The active metals like Potassium ( K ) and Calcium ( Ca) reacts with water at room temperature. However, some metals do not react. For example – Iron reacts with water slowly.

Reaction with Acids

Acids react with metals to liberate hydrogen along with the corresponding salt of the metal.

Zinc + Hydrochloric acid —— Zinc chloride + Hydrogen

Or, Zn + 2HC1 —– ZnCl2 + H2

Zinc + Sulphuric acid —— Zinc sulfate + Hydrogen

Or, Zn + H2SO4 —— ZnSO4 + H2

When a burning matchstick is brought near Hydrogen, it burns with a pop sound.

Reaction with Bases

Metals react with sodium hydroxide to produce hydrogen.

Displacement Reactions

Some metals are capable of displacing other metals from their solutions. For example – Zinc ( Zn) replaces copper from copper sulfate solutions.

Copper Sulphate + Zinc ——- Zinc Sulphate + Copper

CuSO4 + Zn —— ZnSO4 + Cu

More active metals displace less active metals from their solution, in general. In this case, Zinc is more reactive than Cu, so it replaces copper ( Cu ) from a copper sulfate solution. Implying the rule, a more reactive metal replaces a less reactive metal, however, a less reactive metal cannot replace a reactive metal.

Chemical Properties of Non – Metals

Oxidation:  Non-metals react with oxygen to form oxides which are acidic in nature.

Reaction of Non-metals with Water:  Non-metals do not react with water though they may be very reactive in the air. However, some non-metals react with air. For example – Phosphorous.
