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
