buffer-solution
This term is a technical specification used primarily in chemistry and biochemistry. It describes a system designed to maintain homeostasis in a liquid environment, preventing drastic shifts in acidity or alkalinity that would otherwise denature proteins or disrupt chemical reactions.
In a laboratory setting, the term is often shortened to simply "buffer." While "buffer" can refer to any cushioning or protective barrier in other contexts, in a scientific register, it specifically denotes this pH-stabilizing aqueous mixture.
