Electrolysis

Question 1

What happens in aqueous solution

Answer 1

There will be hydrogen ions and hydroxide ions from the water

Question 2

What happens at the cathedral in aqueous solution

Answer 2

If H plus ions and metal ions are present hydrogen gas will be produced if the metal ions forms are more reactive than hydrogen

Question 3

What happens at the anode in aqueous solution

Answer 3

If OH minus and halide ions are present molecules of chlorine bromine iodine will be formed.

Question 4

What happens at the anode in aqueous solution if no halide ions are present

Answer 4

OH minus ions from the water will be discharged and oxygen gas will be formed
