Explanation: When an electric current is passed through acidulated water, it will produce electrolysis . During this process, water is decomposed into hydrogen and oxygen. The positive ions with some move to the cathode while the negative ions will also move to the anode.
What type of chemical reaction take place when electricity is passed through acidulated water?
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.
What happen when electric current is passed through acidulated water write chemical equation?
Electrolysis is passing an electric current through a liquid containing ions so that decomposition reaction takes place. 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.
When electric current is passed through water and are produced?
When electric current is passed through water, it splits up into hydrogen & oxygen . This is called electrolysis of water. Take out carbon rods carefully from two discarded cells.
When electric current is passed?
When an electric current is passed, electrons move from (a) High potential to low potential . (b) Low potential to high potential. (c) Electrons flow from lower to higher potential except through power sources. (d) Electrons flow from higher to lower potential, except through power sources.
What type of chemical reaction takes place when silver bromide is exposed to sunlight?
Light decomposition reaction.
Silver bromide is a light-sensitive compound that is it gets decomposed when exposed to light. So when silver bromide is exposed to sunlight, it gets decomposed to give silver metal and bromine gas is liberated. The reaction is called a photolysis reaction .
What happens when electricity goes through water?
You can become electricity’s path to the ground if you are touching water that touches electricity. Water is an excellent conductor of electricity. You can become electricity’s path to the ground if you are touching water that touches electricity.
Which type of reaction electric current is passed through water?
What type of chemical reactions take place when electricity is passed through water? Explanation: Electrolysis of water is a decomposition reaction .
What happens to electricity in water?
Electrocution in water poses a serious and deadly danger to everyone who swims in a lake or a pool. It occurs when faulty wiring or poorly maintained equipment releases an electrical current into the water which enters people’s bodies, paralyzing their muscles and causing them to drown.
What is the amount of current flowing through an electric?
The SI unit of electric current is the ampere , or amp, which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit Electric current is measured using a device called an ammeter.
When an electric current is passed through a copper wire?
An electric current is passed through a copper wire by connecting its ends to a battery . It is kept between the poles of a strong horseshoe magnet. There is a force on the wire due to the magnet.
Does current flow from low potential to high potential?
The direction of an electric current is by convention the direction in which a positive charge would move. Electric current flows from higher electric potential to lower electric potential . ... So we can say that current flows the same as direction of field and high potential to low potential.
What happens when silver bromide is exposed to sunlight write balanced equation?
Answer Expert Verified
Silver Bromide is exposed to light, it decomposes to silver metal and bromine vapours. 2AgBr (s) ——————- > 2Ag (s) + Br2 (g) . In this reactions, pale yellow colour of silver bromide changes to greyish white due to formation of silver metal.
What happens when AgCl is exposed to sunlight?
When silver chloride is exposed to light, it decomposes to form silver metal and chlorine gas . This reaction is used in black and white photography.
What happens when silver chloride is exposed to air?
When the air silver chloride is exposed to air then the decomposition takes place which breaks the Silver chloride into silver and chloride . When the decomposition takes place the white colour of Silver chloride changes to Grey due to the formation of silver metal.
Does electricity run through water?
Electricity flows through water because it contains ions of dissolved salts and metals. Distilled water, which does not contain impurities, does not conduct electricity.
