Correct option is B
Concentration refers to the amount of solute present per unit volume or per unit mass of the solution. It is a measure of how much solute is dissolved in a specific amount of solvent or solution. Concentration can be expressed in various ways, such as molarity (moles of solute per liter of solution), mass percent, or volume percent. It helps determine the strength of a solution and is a key concept in chemical reactions and processes.
Precipitation refers to the formation of a solid from a solution.
Solubility is the ability of a solute to dissolve in a solvent.
Dissociation is the process in which molecules or ionic compounds split into smaller particles like atoms or ions.
