A solution of CuSO4 is electrolysed for 10 minutes with a current of 1.5 amperes. what is the mass of copper deposited at the cathode?

The mass of copper deposited at the cathode is 0.296 g. Steps to find out the mass of copper deposited at the cathode:

Step 1: Given that:

Time(t) = 10 min = 10 x 60 = 600 sec

Current (A) = 1.5 A

Step 2: Now we have to frame the reaction:

We can formulate the cathode reaction as follows from the aforementioned query:

Cu2+(aq) + 2e- → Cu (s)

Copper ions + Electrons → Copper

In this instance, 2 electrons are transferred.

Step 3: Now we have to find the mass of copper:

The mass of copper we know is 63.5 g mol-1

We know that:

Charge = time x current

Now by substituting the values we get:

Charge = 600 x 1.5

Charge = 900C

Now, the Mass of copper is deposited.

= molar mass x charge/ electrons transferred x Faradays constant

Now by substituting the values we get:

= (63.5 x 900)/ (2 x 96500)

= 57150/193000

= 0.296 g

Consequently, 0.296 g of copper is deposited at the cathode.

Uses of Copper

  • A common agricultural poison and algicide used in water purification is copper sulphate.
  • Copper is an essential component in the production of bronze, even though some people might not think of it as being used for anything besides coins.
  • The first metal that humanity ever worked on was copper, according to history. The Bronze Age got its name when it was realised that metals could be made harder by adding a little tin to create the alloy bronze.
  • It is used for a wide variety of products, including cans, foil for cooking, saucepans, and electricity cables for airplanes and spacecraft.
  • Due to the fact that wire accounts for more than 50% of all copper consumption worldwide, electrical conductivity is particularly crucial.

Summary:

A solution of CuSO4 is electrolysed for 10 minutes with a current of 1.5 amperes. what is the mass of copper deposited at the cathode?

A solution of CuSO4 is electrolysed for 10 minutes with a current of 1.5 amperes. The mass of copper deposited at the cathode is 0.296 g. In addition to defending against lightning-damaged homes and structures, a copper earthing machine may also help those struck by lightning avoid fatalities.
