The purpose of the practical is to form a galvanic couple (battery) from aluminium and steel/copper. Aluminium can be recycled, so the use of aluminium increases for various applications, including the production of batteries (i.e., air batteries). They produce electricity from the reaction of oxygen in the air with aluminium. They also have one of the highest energy densities of all batteries. To understand the mechanism of such batteries, we will perform battery galvanic coupling of two different metals presenting an anode and a cathode. The reduction reaction and the anode oxidation reaction take place on the cathode. This is an electrochemical process where the anode dissolves. The galvanic process is also comparable with the corrosion process, which is always carried out on two pole, cathodic and anodic parts. At anodic part, the metal dissolves; oxidation takes place, while hydroxide ions are released on the cathode as water is reduced.

Workforce in Chemistry

Chemistry is everywhere in our daily life and there are many jobs chemistry graduates do. Around 540,000 students study chemistry, physics, astronomy, and earth science in the EU. Chemistry graduates work as analysts, healthcare scientists, clinical chemists, forensic scientists, nanotechnologists, pharmacologists and toxicologists among others. Jobs for chemists, other scientists and engineers grew by 7% in the past five years. Jobs for technicians in the field grew by 2%. Overall, they account for 7% of all jobs in the EU. As of 2016, around 15 million European science and engineering workers are employed. They work in a variety of sectors, many of which related with chemical industry, such as agrochemicals, metallurgical, petrochemicals, pharmaceuticals, and plastics and polymers. Many also work in professional services, utilities, and in the education systems. In the next years, jobs for chemistry scientists, other researchers and engineers will increase by 13%, and jobs for science and engineering technicians will increase by 2%.
