When electricity is passed through an aqueous solution of sodium chloride the products formed are?

When electricity is passed through an aqueous solution of sodium chloride, the three products are obtained which is hydrogen, chlorine and sodium hydroxide.

What is formed when electricity is passed through aqueous solution of sodium chloride?

When an electric current is passed through concentrated sodium chloride solution, hydrogen gas forms at the negative electrode , chlorine gas forms at the positive electrode, and a solution of sodium hydroxide also forms.

IT\'S FUNNING:  Question: Which resource produces the cleanest energy quizlet?

What happens when aqueous solution of sodium chloride is electrolysed?

Electrolysis of aqueous sodium chloride: Electrolysis of aqueous NaCl results in hydrogen and chloride gas. … At the cathode (C), water is reduced to hydroxide and hydrogen gas. The net process is the electrolysis of an aqueous solution of NaCl into industrially useful products sodium hydroxide (NaOH) and chlorine gas.

When a current is passed through the aqueous solution of NaCl?

When an electric current is passed through an aqueous solution of sodium chloride, sodium ions move towards cathode and chloride ions move towards anode.

When an electric current is passed through an aqueous solution of sodium chloride its pH?

When an electric current is passed through an aqueous solution of sodium chloride. During electrolysis of NaCl(aq),H+ ions are discharged at cathode and the pH of solution increases due to decrease in [H+] .

When electricity is passed through an aqueous solution of sodium chloride it decomposes to form sodium hydroxide?

Hint:When electricity is passed through an aqueous solution of sodium chloride (called brine), it decomposes to form sodium hydroxide. The process is termed as chlor alkali process. The chemical equation is as follows: 2NaCl(aq)+2H2O(l)→2NaOH(aq)+Cl2(g)+H2(g.

When electricity is passed through an aqueous solution of sodium chloride three products are obtained then why is the process called Chlor Alkali process?

When electricity is passed through an aqueous solution of sodium chloride, the three products are obtained which is hydrogen, chlorine and sodium hydroxide. But this process is called chlor-alkali process because here, chlor stands for chlorine and alkali for sodium hydroxide.

When an aqueous solution of sodium chloride is electrolysed using platinum electrodes the ions discharged at the electrodes are?

In electrolysis of NaCl when Pt electrode is taken then H2 is liberated at cathode while with Hg cathode it forms sodium amalgam because : a) Hg is more inert than Pt.

What happens when aqueous solutions are electrolysed using inert electrodes?

There are a variety of ways of carrying out electrolysis. This investigation looks at what happens to aqueous solutions when they are electrolysed using inert electrodes. … In all cases where aqueous solutions are electrolysed, water will also be electrolysed, producing hydrogen ions and hydroxide ions.

How does electrolysis happen?

electrolysis, process by which electric current is passed through a substance to effect a chemical change. … The process is carried out in an electrolytic cell, an apparatus consisting of positive and negative electrodes held apart and dipped into a solution containing positively and negatively charged ions.

When an electric current is passed through an aqueous solution of the following?

An aqueous solution of sodium chloride conducts electricity because it is a soluble ionic compound when dissolved in water.

What happens when electricity is passed through an aqueous solution of brine?

When electricity is passed through brine it decomposes to form sodium hydroxide along with the evolution of chlorine gas at anode and hydrogen gas at cathode.

When current is passed through aqueous solution of NaCl which gas is liberated?

An aqueous solution of NaCl containing 5.85 g/L of NaCl was electrolysed by using platinum electrodes. Hydrogen and chlorine gases evolved at the cathode and anode respectively. Calculate the pH of the solution after electrolysis assuming complete electrolysis of NaCl.

IT\'S FUNNING:  What are the risks of electrical cardioversion?

When an electric current is passed through an aqueous solution of KCl?

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.

Which of the following aqueous solution is called Brine?

An aqueous solution of sodium chloride is called Brine.
