Final answer:
The matching word for "water" in the context of the options provided is (a) dilute, which refers to the process of adding water to a solution to decrease the concentration of solutes, resulting in a 'diluted' solution. Option a
Step-by-step explanation:
The word "water" in the context of the provided options is best matched with option (a) dilute. Dilution is a process in chemistry where the concentration of a solution is reduced by adding more solvent. In this case, water is often the solvent used to dilute solutions.
An example to illustrate dilution is a glass of iced tea that becomes less concentrated in flavor as the ice melts because the melting ice adds water to the iced tea, increasing its volume and thus diluting the taste of the tea.
A diluted solution has a lower concentration of solutes compared to a concentrated solution. Therefore, when we refer to the act of adding water to a solution to decrease the concentration of solutes, we are describing the process of dilution. The term dilute can also be used as a qualitative descriptor for a solution that contains a solute at a relatively low concentration. Option a
