Q7: What type of chemical reactions take place when electricity is passed through water? Explanation: Electrolysis of water is a decomposition reaction.
Why no chemical reaction took place when electric current was passed through pure water?
Solution : (a) because pure water (or distilled water) is a non conductor of electricity. <br> (b) Sulphuric acid. <br> (c) Sulphuric acid is an electrolyte. The addition of a little of sulphuric acid made water a good conductor of electricity.
What happens when electric current is passed through water class 8?
Solution: When an electric current is passed through water, then water dissociates into hydrogen and oxygen. This is an example of the chemical effect of electric current.
What type of chemical reactions take place when electricity is passed through water ?( A displacement B combination C decomposition D double displacement?
What type of chemical reactions take place when electricity is passed through water? Explanation: Electrolysis of water is a decomposition reaction.
When electric current is passed through acidulated water decomposition of water takes place in this reaction hydrogen and oxygen gas are formed True or false?
Answer. It is decomposition reaction because when electricity is passed through the water a single compound split into two elements hydrogen and oxygen so it is called decomposition reaction.
When electric current is passed through acidified water then what is produced at anode and cathode?
Answer. Explanation: When an electric current is passed through acidified water, it decomposes to give hydrogen and oxygen gas. The hydrogen gas is obtained at the cathode and the oxygen gas is obtained at the anode.
What type of chemical reactions take place when electricity is passed through water a displacement B combination C decomposition D double displacement?
What type of chemical reactions take place when electricity is passed through water? Explanation: Electrolysis of water is a decomposition reaction.
What is electrolysis Class 9?
What is Electrolysis? Electrolysis is defined as a process of decomposing ionic compounds into their elements by passing a direct electric current through the compound in a fluid form. The cations are reduced at cathode and anions are oxidized at the anode.
Which of the following is a displacement reaction?
Which of the following is a displacement reaction? Explanation: Sodium displaces hydrogen to form sodium hydroxide. Hence, it is a displacement reaction.
Which of the following are combination reaction?
Solution : A reaction in which two or more reactants react together to form a single product, is called a combination reaction. In reaction (ii), `MgO and H_(2)O` combine to form `Mg(OH)_(2)` and in reaction (iii), Al and `O_(2)` combine to form `Al_(2)O_(3)`.
When electric current is passed through acidulated water displacement of water takes place * True or false?
When electric current is passed through acidulated electrolysis of water takes place. Explanation: When an electric current is passed through acidulated water, it will produce electrolysis. During this process, water is decomposed into hydrogen and oxygen.
When electric current passed through acidified water water breaks down to form hydrogen and oxygen this is *?
Answer: When an electric current is passed through acidified water, It gives H+ and OH- ions. This process is called the chemical effect.
When electric current is passed through acidulated water displacement of water takes place * True False?
When electric current is passed through acidulated electrolysis of water takes place. Explanation: When an electric current is passed through acidulated water, it will produce electrolysis. During this process, water is decomposed into hydrogen and oxygen.
When electric current is passed through acidified water then hydrogen and water are formed what type of effect is illustrated by this statement explain the process?
When electric current is passed through acidified water, it dissociates water into H+ and OH– ions. This process is called chemical effect.
What is electrolysis for class 10th?
What is Electrolysis? Electrolysis is defined as a process of decomposing ionic compounds into their elements by passing a direct electric current through the compound in a fluid form.
How can an iron key be electroplated with copper?
The iron key will be taken as the cathode (negative electrode ) and the copper to be electroplated on iron key to be made the anode (positive electrode). When we open the electricity, then copper ions are deposited on the negative electrode and in this way copper is electroplated on the iron key.

Which of the following is a combination reaction Class 10?
Solution : A reaction in which two or more reactants react together to form a single product, is called a combination reaction. In reaction (ii), `MgO and H_(2)O` combine to form `Mg(OH)_(2)` and in reaction (iii), Al and `O_(2)` combine to form `Al_(2)O_(3)`.
What type of reaction is Fe cuso4 -> feso4 CU?
displacement reaction Fe + CuSO4(aq) → FeSO4(aq) + Cu(s) The type of reaction is a displacement reaction. In this reaction, the highly reactive metal iron replaces the Copper in copper sulphate by giving up two electrons and gets oxidized and forms a new compound called ferrous sulphate.
What is electrolysis definition Class 8?
Answer: Electrolysis is the production of a chemical reaction by passing an electric current to liquid containing ions.
What is electrolysis of water class 8?
Electrolysis of water is the process by which water is decomposed into oxygen and hydrogen gas, when electric current is passed through it. Water molecule is decomposed in to H+ and OH- ions, when electric current is passed through it.
How can you electroplate an Aluminium chain with gold?
Connect the gold with possitive terminal of the battery. We can say that the Aluminium chain is the Cathode and gold is the Anode. Dip both ( Anode & Cathode ) into the salt solution of gold and after some time we can see that the gold has been deposited in the Aluminium chain. Hope you found this informative!
