Titration
Definition
Titration is an analytical method used in chemistry to determine the concentration of an unknown solution using a known concentration of another solution.
Analogy
It's like filling up your car's gas tank. You don't know how much gas is left in the tank (unknown solution), but you can find out by seeing how much more it takes to fill it up (known solution).
