• Electroplating is the process of coating one
  metal object by another, works by electrolysis,
  which is when electricity is used to drive
  chemical reaction
• So here we will be looking at three main aspects
  that is,
• Why we electroplate?
• What is the process?
• What are the required conditions for
  electroplating?

Why we electroplate ?

• There are several reasons for electroplating, it
  can be aesthetics or protection or both.
• The metal can be made aesthetics by making it
  shiner or giving attractive colour to the metal
  by coating. For example, jewellery is often
  plated with gold or silver to look attractive.
• Electroplating can also be used for protection as
  it may help prevent corrosion, rusting or just
  general wear and tear. Car rims are electroplated
  for both shininess and protection.
• Chromium which is commonly known as chrome,
  nickel, tin and zinc and cadmium are often used
  to play copper, iron and steel objects. Tin cans
  are actually made of steel but have thin tin
  coatings, the astronaut who made the first
  American spacewalk in 1965, was wearing a gold
  plated visor to protect his eyes from solar
  radiation.

How does electroplating work ?

• In these process of electroplating an electric
  current is passed from a solution that conducts
  electricity. An electrolyte to create these
  current two electrodes are dipped into the
  electrolyte solution and connect to the power and
  battery supply
• When the current is turned on the electrodes gain
  a charge, the positively charged electrode is
  called anode and negatively charged electrode is
  called cathode. The electrode and electrolytes
  are chosen carefully based upon, what metal you
  are plating with. If you want to copper plate
  another metal, you use copper based electrolyte
  solution and have a copper anode. The copper for
  plating comes from the electrolyte solution,
  which in turn has its stops replenished by the
  copper anode

For exampleWe want to copper plate some
brassSo we have A copper anode A brass cathode
Copper based solution for the electrolyte
(copper sulphate solution) Copper sulphate
solution contains copper sulphate ions and
sulphate colourless ions. The copper ions are
positively charged and so attracted to negatively
charged brass cathode
9
The copper ions are deposited onto the brass,
producing thin copper plate. The positively
charged copper ions gains electrons, which is
known as reduction. The sulphate ions are
negatively charged and so get attracted to the
positively charged copper anode, the current
supplied to the anode causes the copper atom to
oxidize which is lose electrons and then dissolve
into the electrolyte solution. So the copper
ions move from the anode to cathode in the
solution and the electrons move from the anode to
the cathode by the long wire. The copper anode
wire gradually dissolves to replenish the copper
ions in the electrolyte solution, so the
solutions stays in the same concentration If
another matter was used at the anode then the
copper sulphate solution, would gate pale or less
concentrated

• Few things which are needed to be considered?
• the speed of the electroplating process depends
  on the speed of the electric current
• one way to increase the current is by increasing
  the concentration of ions in the solution
• It is also important to choose you metal
  carefully in electroplating, not all metal alloy
  with each other. For instance steel has to be
  copper before plating it with silver because
  steel does not directly alloy with silver
• There are also environment concerns associated
  with some metals, chrome plating for examples
  created waste that is harmful for humans and
  animals, waste products must be treated
  accordingly to make sure that they are safe which
  can be very expensive
• Finally, and most importantly, for current to
  flow, the ions need to be able to move so the
  compound must be in molten state or dissolved in
  a solution
