What will happen when zinc rod is dipped in copper sulphate solution?

When a zinc rod is dipped in a solution of copper sulphate, zinc, being a more reactive metal than copper, will displace copper from copper sulphate solution. The red-brown colour of copper will be deposited on the zinc rod. …

What happens when a rod of zinc metal is dipped into a solution of copper sulphate Class 10?

Answer: When zinc is added to copper sulphate (CuSO4) solution due to more reactivity of zinc, copper is replaced by zinc and forms zinc sulphate. During the process, the colour of the solution changes from blue to colourless.

What happens when a rod of zinc metal is dipped in a solution of silver nitrate?

Explanation: This single replacement reaction will produce silver metal, Ag , and aqueous zinc nitrate, Zn(NO3)2 . Zinc is above silver is the metal reactivity series, so it will replace silver in silver nitrate.

What happens when copper rod is dipped in?

– As per the electrochemical series the reduction potential of copper is high (more) when compared to iron. – Thus the copper cannot displace the iron from its salt solution due to its high reduction potential value. – Therefore there is no reaction when copper rod is dipped in iron sulphate solution.

When a zinc rod is dipped in a solution of copper sulphate zinc rod gets dissolved and copper gets deposited at the bottom of the vessel?

The reason behind all these factors is the displacement reaction. Placing a Zinc rod in a CuSO4 solution will undergo a reaction according to which Zn will dissolve because it reduces the Cu2+ ions to the elemental metal. Due to which, the blue color will fade away and the copper metal will get deposited.

What happens when a zinc rod is dipped in copper nitrate solution *?

Statement 1 : A piece of zinc placed in a blue copper nitrate solution will displace the copper from the solution, producing copper metal and a colorless Zn2+ solution.

What happens when zinc metal reacts with any solution?

Zinc reacts with hot and conc. sodium hydroxide to form sodium zincate with the liberation of hydrogen.

What happens when zinc reacts with metal?

Acids and Bases React with Metals For example, zinc metal reacts with hydrochloric acid, producing zinc chloride and hydrogen gas. Bases also react with certain metals, like zinc or aluminum, to produce hydrogen gas. For example, sodium hydroxide reacts with zinc and water to form sodium zincate and hydrogen gas.

What happens when zinc metal reacts with Dil?

hydrochloric acid to form zinc chloride and hydrogen gas.

What happens when you put zinc in copper?

That is why copper(II) ions can act as an oxidizing agent when put into contact with zinc metal. However, no reaction will occur if a strip of copper metal is placed into a solution of zinc ions, because the zinc ions are not able to oxidize the copper. In other words, such a reaction is nonspontaneous.

What happens when copper rod is dipped in a solution of iron II sulphate for about twenty minutes Justify your answer?

Nothing would happen. Copper is less reactive than iron. It cannot displace iron (II) sulphate.

What happens when zinc metal is dipped in copper sulphate solution give the chemical reaction involved state which is more reactive zinc or copper?

Answer: When Zn metal is dipped into cuso4 solution Zn is combined with so4 and cu is displaced, this is a best example of displacement reaction. Chemical equation of this reaction is Zn+Cuso4=Znso4+Cuso4 Hence it is automatically proved that Zn is more reactive than Cu.

What happens when a zinc rod is dipped in copper sulphate solution?

When a zinc rod is dipped in a solution of copper sulphate, zinc, being a more reactive metal than copper, will displace copper from copper sulphate solution. The blue colour of the copper sulphate solution gradually fades due to the formation of the green-coloured zinc sulphate. The red-brown colour of copper will be deposited on the zinc rod.

How long does it take for zinc to react with copper?

The solution is initially blue in color. A dark coating of copper metal appears on the zinc within two minutes and when 45 minutes have elapsed, there is a thick coat of copper metal powder on the zinc strip and the blue color of the solution has lightened considerably.

What is the reaction between zinc and copper sulfate pentahydrate?

The reaction with zinc is a displacement reaction: The reaction with zinc, if complete, results in zinc sulfate dihydrate (shown above). In solution, this is colourless, so the blue colour of the copper sulfate pentahydrate disappears. Learn to make nutritional assessments and dietary analyses.

What is the reduction potential of copper II sulfate?

Since the copper(II) ion has substantially greater reduction potential (+0.15 V) than zinc ion (-0.76 V), it is readily reduced by zinc metal. The blue color of the aqueous copper(II) sulfate solution is due to the presence of the hexaaquacopper(II) ion in water.
