First of all, what is electrolysis?

Electrolysis is the process of breaking down ionic substances using direct current.

Important points about electrolysis

→ Ionic substances contain particles called ions.

→ Electricity is the flow of electrons or ions. For electrolysis to work, the compound must contain ions. The ions must be free to move for electrolysis to occur and it can happen by melting or dissolving an ionic substance in water.

→ Positively charged ions move to the negative electrode. They receive electrons and are reduced. The positive ions move towards the negative electrode because they want to cancel each other out.

→ Negatively charged ions move to the positive electrode.  They lose electrons and are oxidised. The substance that is broken down is called the electrolyte (an electrolyte is just a liquid or solution that can conduct electricity) . The negative ions move towards the positive electrode because they want to cancel each other out.

Cathode = Negative electrode

Anode = Positive electrode

Metal ions form at the cathode and non-metal ions form at the anode

How I remember if an element is oxidised or reduced is by remembering OIL RIG

OIL = Oxidation is Loss (of electrons)

RIG = Reduction is Gain (of electrons)

The answer to your question

1) The first step would be to clean the metal ring and sand it down because when the metal atoms from the electrolyte are deposited onto the ring, they will form a weak bond and they may simply 'fall' off. Also this could affect conductivity and the whole experiment. The more things you do accurately now, the more accurate your result will be.

2) You want to put the solution you are given in to the tank your going to be using.

3) This is basically the main part, you want to set up the circuit, I have attached a diagram at the bottom to show you the circuit. The copper rod will be the anode and the metal ring will be a cathode (ignore the elements).

4) Now turn on the circuit and you will start to see the solution spilt with the the solution now being split some going to the anode and some going the cathode.

5) Then a thin layer should form on the electrode.

Hope this helps :)

A single nucleotide is made up of the three parts known as phosphoric acid, deoxyribose and a nitrogenous base

What three parts are in a single nucleotide ?

The part of the nucleotide that determines the genetic information is the Nitrogenous base. There are four different types of nitrogenous bases: adenine (A), guanine (G), cytosine (C), and thymine (T).

The part of the nucleotide that provides the structure and stability of the molecule. The sugar in DNA is deoxyribose, while the sugar in RNA is ribose.

The Phosphate group is part of the nucleotide that provides energy and helps to link nucleotides together. It is also known as phosphoric acid.
