Understanding pH buffering systems and pKa values
Eric dives deep into alkalinity chemistry, explaining how pH buffering systems work, and the concept of a pKa value.
Show Notes
00:00 - Introduction
03:16 - pH buffering
04:43 - Bicarbonate, cyanurate and borate
06:41 - pH is based on H2O and hydrolysis
09:56 - Carbonate alkalinity means dissolved CO2 determines pH
11:51 - Bicarbonate converts into carbonate at 8.3 pH
13:22 - High TA, more buffering capacity, more acid demand
15:19 - Acids and conjugate bases
18:16 - pKa values and buffering strength
20:52 - What does pKa stand for?
23:05 - Closing
