Solution concentration refers to the amount of solute present in a given volume of solvent or solution. It is commonly expressed in various units, such as molarity (moles of solute per liter of solution) or percentage concentration (mass of solute per total mass of solution). Understanding concentration is essential in fields like chemistry and biology, where precise measurements are crucial for reactions and processes. Different methods can be used to determine solution concentration, including dilution and titration. Dilution involves adding more solvent to decrease concentration, while titration is a technique used to find the concentration of a solution by reacting it with a solution of known concentration.
