Chapter 26, Problem 8MC
Summary Introduction
Introduction:
Water treatment is the process of treating the water to improve its quality and make it suitable for use. Water contamination is the presence of any substance, whether it is natural or artificial, in water which makes it unsuitable for use. Not all contaminants pollute the water.
Chemical treatment is the use of chlorination for treating wastewater and drinking water. In this process, chemicals such as oxidizing agents, iodine, and chlorine are used. Addition of these compounds helps in reducing the growth of microbes and kills them. It is a form of disinfection.

They grew bacterial colonies of Salmonella typhimurium in petri dishes labelled A, B and C. The Petri dishes were kept at 36°C for 48 hours, with scientists observing the bacteria every 24 hours. The results for this investigation are below. Petri dish A B с Treatment Was subjected to ionising radiation followed immediately by a dose of antibiotic X An equal amount of antibiotic X was added (as was added to Petri dish A) Was given neither ionising radiation nor antibiotic X After 24 hours Small spots of growth on surface No growth Growth across whole surface After 48 hours (ii) Identify the purpose of petri dish C.
