Answer: A current will electrolyze molten KCl, liberating liquid potassium (unless the salt’s temperature is > 1052 K, the boiling point of potassium) and gaseous chlorine.
When an electric current is passed through an aqueous solution of sodium chloride?
When electricity is passed through an aqueous solution of sodium chloride, it gives hydrogen, chlorine and sodium hydroxide as a product. The balanced chemical equation is, This process is called as Electrolysis of Brine.
What happens at cathode when an electric current is passed through an aqueous solution of an acid?
When electricity is passed through an aqueous solution of an acid, the H+ ions reach the cathode and each H+ ion picks up one electron from the cathode to form H2 gas. Because of this reaction, an aqueous solution of acid conducts electricity.
What happens when electricity is passed through an aqueous solution of sodium chloride write the chemical equation of the reaction involved?
An aqueous solution of NaCl on electrolysis gives H2(g),CI2(g) and NaOH according to the reaction: 2CI−(aq)+2H2O=2OH−(aq)+H2(g)+CI2(g)
When electricity is passed through an aqueous solution of sodium chloride What is XY and where it will be produced?
Answer: X is Sodium hydroxide. Y is Chlorine gas.
Which of the following will not conduct electricity in aqueous solution?
Sugar solution does not form ion, hence it does not conduct electricity in aqueous solution.
When electricity is passed through an aqueous solution of sodium chloride three products are formed?
When electricity is passed through an aqueous solution of sodium chloride, the three products are obtained which is hydrogen, chlorine and sodium hydroxide.
What happens when an acid is added to an aqueous solution of base?
Acids and bases also react with each other to form compounds generally known as salts. … Many acids are simple compounds that release a hydrogen cation into solution when they dissolve. Similarly, Arrhenius defined a base as a compound that increases the concentration of hydroxide ion (OH−) in aqueous solution.
Does an aqueous solution of an acid conduct electricity?
Therefore, we can conclude it as an aqueous solution of an acid that conducts electricity because, in water, an acid (HCl) dissociates to give ions. Since the current is carried out by the movement of ions, an aqueous solution of acid conducts electricity.
Why does an aqueous solution of base conduct electricity?
The charged particles ions are present in the aqueous solutions Hydrogen and hydronium ions. These ions carry electric currents thus acids conducts electricity. … Bases are also electrolytes that give ions in aqueous solutions and these ions help to conduct electricity.
When current is passed through a solution of NaCl?
When current is passed through molten NaCl i.e. sodium chloride, it decomposes into sodium and chlorine gas. Both sodium and chlorine gas move towards the electrode opposite to their own charge and either loses an electron or gains one.
Which one of the following is not obtained from the electrolysis of an aqueous solution of NaCl?
a-Nacl, b-H2,c-Naocl,d-Cl2. these are the products obtained from electrolysis of brine solution. But the chlorine will react with sodium hydroxide to form sodium chlorate(I) NaOCl. Hence the correct option is a) NaCl which is not formed when the products obtained from an electrolysis of brine are mixed.
What happens when brine is electrolysed with platinum electrode?
The half-equations for the electrolysis of sodium chloride solution (the electrolyte brine). The negative (–) cathode attracts the Na+ (from sodium chloride) and H+ ions (from water). … The chloride ions are oxidised by electron loss to give chlorine molecules at the positive electrode which attracts negative ions.
