1.1 Background of the Study
Chemistry is a branch of science that deals with the fundamental materials composing the entire physical world. Chemistry as an aspect of science, studies the composition, properties and uses of matter (Ababio, 2010). It probes into the changes that matter undergoes under different conditions. Our environment is made of matter; chemistry therefore deals with the study of our environment and explaining things that are happening. For examples rusting of iron nails, burning of substance, photosynthesis and many more. In addition, most of the things that can be touch, taste or smells are chemicals, such as laundry detergent and drugs, which are by product of chemistry.
Similarly, chemistry plays a vital role in other Scientific and technological disciplines such as agriculture, biochemistry, engineering, medicine, microbiology, and pharmacy among others. That is why it becomes compulsory for students to have sound background knowledge of chemistry up to secondary school certificate level before undertaking courses in any science related disciplines.
