Electrolysis is the process in which a chemical reaction takes place at the expense of
electrolysis process electrical energy converted In this into chemical energy.
Complete systematic equipment set up for electrolysis is known as
Electrolytic cell means there is an arrangement of cathode, anode, cation, anion, battery etc.
Oxidation occurs at
Electron removal is responsible for reduction and it occurs at cathode.
In the electrolysis of a Solution of potassium iodide with phenolphthalein indicator, a pink colour appears at the negative electrode. Which one of the following is the fact?
Hydrogen gas is being produced at the cathode and iodine at the anode
Cathode is electrically
Cathodes are connected to the negative terminal of the battery and attract cations.
Which of these is not an application of electrolysis?
Others are involved in electroplating an application of electrolysis
Anode is electrically
Anodes are connected to the positive terminal of the battery and attract anions
For electrolysis, we use the compound which should be a
The Only conductor can conduct current through ions.
When aqueous Solution of NaCl is electrolyzed
Cathode reaction: Na+ + e → Na
Which metal is used in electroplating cans to store food?
Sn is mainly used in electroplating can.
Which one of the following statements is NOT correct?
Not only molten as well as aqs.
Which pair of electrolytes is not inert?
Both are metallic in nature
To prevent iron from corrosion it is electroplated with
Zinc is less reactive metal and can resist corrosion.
Pure water is a good conductor of electricity. The statement is _.
Pure water has lack of ions for conduction
Which of the following substance is not a good conductor of electricity?
Good conductor means that dissociate into ions in aqs. Medium to conduct electricity. Rubber has no such property.
When fused PbBr2 is electrolyzed
Cathode reaction: Pb2 + 2e → Pb
What are the ions present in water?
H2O → H+ + OH-
Reduction occurs at
Electron acceptance is responsible for oxidation and it occurs at anode
In electrolysis of pure ionic molten compounds, metal is formed at
Cathode attracts cation. Metals are generally converted to cation and hence deposited at cation
Most liquids that conduct electricity are Solutions of
They must exist in aqs. medium so that they form ions and continues condition as well as electrolysis.
Ions discharged in electrolysis depends on the factor is
ions discharge is depend upon Relative electrode charge
The decomposition of liquid compound on passing an electric current through it is known as
Electrolysis is the process by which decomposition of liquid takes place by passing electric current through it.
The whole apparatus of electrodes, electrolytes and vessel containing them is called
Apparatus of electrodes, electrolytes and vessel containing is called Voltammeter.
In an electroplating experiment a steel cathode and a Solution of nickel sulphate electrolyte is used. What type of anode was most likely used?
Electrolyte and electrode of same metal are preferable so that more same ions are formed. As we take nickel sulphate electrolyte, so Ni electrode is preferable.
Cathode production electrolysis of zinc iodide is
Cathode reaction: Zn2 + 2e → Zn
