Acid-Base Pair: An acid-base pair consists of two substances that differ only by one proton. In our analogy, this would be like recognizing that before and after throwing/catching, each friend still remains part of the same game of catch.
pKa Value: The pKa value measures how readily an acid donates its protons. It's akin to assessing how willing our first friend is to throw his ball.
A buffer solution resists changes in pH when small amounts of acids or bases are added. Imagine if more friends joined your game but rules stayed consistent โ thatโs what buffers do for pH levels!
