What would you observe when zinc is added to a solution of iron sulphate

When zinc is added to a solution of iron (II) sulphete, then the greenish colour of iron (II) sulphate solution fades gradually due to the formation of colourless zinc sulphate solution, and iron metal is deposited on zinc: `underset("Iron (II) sulphate (Greenish solution)")(FeSO_(4)(aq))+underset("Zinc (Silvery-white)")(Zn(s))tounderset("Zinc sulphate (Colourless solution)")(ZnSO_(4)(aq))+underset("Iron (Grey)")(Fe(s))`.

Q.1. (iv) Answer: Generally, metals are considered a good conductor of heat and electricity. But mercury and lead show slight exception as they are a poor conductors of heat. Q.2. Answer: Malleable substances are the substance which can be beaten in order to convert them into sheets. Generally, all metals are considered to be malleable in nature. For example silver, iron, etc. Gold has the highest malleable property as one single gram of gold can be beaten into a sheet of 1 square meter. Ductile substances are substances which can be drawn into wires. All the metals like gold, copper are dectile in nature. Moreover, the wires for transfer of electricity are made of copper.

It reacts rapidly with the oxygen and thus cannot be kept in air as it will explode. So it is better to store in a liquid. Further the density of sodium is less than that of water so it will float on the surface. So water is not a good solvent for the purpose. So sodium is kept in kerosene oil.

What would you observe when zinc is added to a solution of iron(II) sulphate? Write the chemical reaction that takes place. ANS. ) When Zinc is added to a solution of Iron (II) sulphate, a displacement reaction takes place. • Zinc being a more reactive metal than Iron (as zinc lies about iron in the reactivity series), will replace iron from its salt solution. • The reaction produces Zinc sulphate + Iron. • The Iron settles as a grey precipitate and a colourless solution of zinc is formed. • The reaction can be given as,

Solution: concept - Displacement reaction is a chemical reaction in which one element is replaced by another element in a chemical reaction as per the reactivity series. The reactivity series is a chart in which metals are arranged in order of their reactivity. The metals which are found at the bottom of the reactivity series are the least reactive. Now, a more reactive metal displaces the less reactive metal from its salt solution and this reaction is known as the displacement reaction. Now, when Zinc is added to a solution of Iron (II) sulphate, the reaction takes place as- Zn + Fe SO 4 → Zn SO 4 + Fe Therefore, Zn displaces Fe from its solution. When zinc is added to Fe SO 4 solution, the colour changes from green to colourless. Fe SO 4 is green in colour and Zn SO 4 solution is formed and greyish black iron metal is deposited. Hence, the correct option is (1).
