What causes bubbles to form when electricity is passed through acidic water?
The bubbles are hydrogen and oxygen, formed from the electrolysis of the water by the electric current. Oxygen gas accumulates at the anode. Hydrogen gas accumulates at the cathode.
What happens when electric current is passed through acidified water?
When electric current is passed through acidified water (a mixture of water and an acid such as HCl), electrolysis occurs. The water molecules (H2O) are split into hydrogen gas (H2) at the cathode and oxygen gas (O2) at the anode. The overall reaction can be represented as: 2H2O(l) -> 2H2(g) + O2(g).
When electric current is passed through water which gas is produced on cathode?
When electric current is passed through water, hydrogen gas is produced at the cathode. This is because water molecules (H2O) are split into hydrogen (H2) and oxygen (O2) gases through electrolysis. The hydrogen gas is evolved at the negative electrode, which is the cathode.
What will happen to water molecule when electricity is passed through water during electrolysis?
During electrolysis of water, the water molecule will be split into its constituent elements: hydrogen and oxygen gas. This is due to the electrical current breaking the bonds between the hydrogen and oxygen atoms in the water molecule, resulting in the release of hydrogen gas at the cathode and oxygen gas at the anode.
Can water be broken down by chemical?
Water can be broken down by the chemical process called electrolysis. An electrical current is passed through water with an electrolyte added to it. The electrical current breaks down the water into hydrogen and oxygen gas that bubble up from the electrodes in the water.
What happen when electric current passes through acidified water?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What happen when electric current is passed through slightly acidic water?
When electric current is passed through slightly acidic water, it ionizes the water molecules into hydronium (H3O+) and hydroxide (OH-) ions. Hydrogen gas is produced at the cathode due to reduction of hydrogen ions, while oxygen gas is produced at the anode due to oxidation of hydroxide ions. The overall reaction is 2H2O(l) -> 2H2(g) + O2(g).
What happen when electric current is passed through water'?
when electric current is passed through acidified water hydrogen gas is released at the cathode..
What causes water to become too acidic and why does this happen?
Water becomes too acidic when there is an increase in the concentration of hydrogen ions (H) in the water. This can happen due to various factors such as acid rain, industrial pollution, and natural processes like volcanic eruptions. The excess hydrogen ions lower the pH of the water, making it more acidic.
What makes hot water sticky or oily out of the tap?
This will happen lots of times when the water is acidic with a low PH
Predict what will happen to the pH of an acidic solution if you add water to it?
Adding water to an acidic solution will dilute the concentration of hydrogen ions, causing the pH to increase. This is because the addition of water reduces the relative amount of H+ ions, making the solution less acidic.
What causes bubbles to form when electricity is passed through acidic water?
The bubbles are hydrogen and oxygen, formed from the electrolysis of the water by the electric current. Oxygen gas accumulates at the anode. Hydrogen gas accumulates at the cathode.
What happens when electric current passed through acidulated water?

Why the water gets heated when current is passed through carbon rods in it?
The carbon rods have electrical resistance. Thisi causes them to heat when current is passed through them. The water gets heated by the carbon rods.
What are the products formed when an electric current is passed into acidified water?
Hydrogen and oxygen
When electric current is passed through a strong solution of brine then what will happen?
When electric current is passed through a strong solution of brine (sodium chloride in water), electrolysis occurs. Chlorine gas is produced at the anode, sodium metal at the cathode, and sodium hydroxide remains in solution. This process is known as the chlor-alkali process.
Why is groundwater acidic?
One cause of acidic ground water is polluted rain water, which can be acidic.
