👉 Subsaturation is a state of saturation where there is no more increase in concentration or volume of a substance without further addition. It occurs when a substance has reached its maximum capacity and cannot be increased any further, as it would result in an undesirable change in behavior. For example, if you have a solution that contains 20% sodium chloride (NaCl), the amount of NaCl that can be added to this solution without changing its concentration or volume is 19.67%,
