Final answer:
Chlorine is consumed when it reacts with organic materials, such as in water purification and bleaching, which is true. As an oxidizing agent, chlorine changes compounds by reacting and binding with different elements, resulting in its consumption.
Step-by-step explanation:
Indeed, the statement is true: chlorine is consumed when it reacts with organic materials. Chlorine is a powerful oxidizing agent and is extensively used for water purification and bleaching processes. When chlorine is added to water, it reacts with organic matter, forming hypochlorous acid which oxidizes colored substances into colorless ones.
This reaction results in the consumption of chlorine. For instance, in water treatment, chlorine is important for destroying bacteria and other microbes. In the textile industry, chlorine is used to bleach wood pulp and cotton cloth.
Furthermore, chlorine reacts with hydrocarbons in various chemical processes, replacing hydrogen atoms with chlorine to produce a variety of compounds, including tetrachloride (CCl4), chloroform (CHCl3), and ethyl chloride (C2H5Cl), which again involves the consumption of chlorine.
