acid. CH3COOH H+(aq) + CH3COO-(aq) approx 99% approx 1% Conductivity Any solution’s ability to conduct electricity is conditioned by the concentration of ions it contains. A strong acid has more ions than a weak one‚ and so it’s solution will be a better electrical conductor than a weak acid. The same goes for strong/weak bases. The conductivity may be measured using a power pack and two graphite electrodes connected to an ammeter. The apparatus is assembled and current

This essay will describe the electrochemical processes that allow an Action potential to occur in a neuron. This will be achieved by firstly‚ defining the purpose of neurons in the body along with a description of the components within a neuron and how they enable information to be passed through the cell membrane and on to other neurons. Secondly‚ the resting potential of a neuron will be explored with relation to the concept of selective permeability and the purpose of the Sodium - Potassium
