Wow I have three associate degrees in horticulture and a bachelor's in plant science. I didn't understand a lot of what you were explaining but I definitely have a way better understanding of alkalinity in a pond, now. Thanks you!

The slide shown at 11:05 shows (at the bottom of the page) a definition of Alkalinity being [HCO3-] + 2[CO3-2] + [OH-] + [H+] - note in particular that the carbonate concentration is shown as multiplied by 2. In the following slide, the factor of 2 on the carbonate concentration is absent.Which is correct?

Belinda, do you know of the forumla to calculate Alkalinity if I have ph, co2, temperature and salinity. Can this be done or do I need any other inputs? This is for determining alkalinity in saltwater.

Just to make it more complicated: the explanation at 4 to 6 minutes that the precipitation of CaCO3 will drive the dissolution of atmospheric CO2 in water is not correct. The opposite is true: in the ocean, for every mole of CaCO3 precipitated, 0.6 moles of CO2 are RELEASED into the atmosphere. CaCO3 precipitation decreases the pH of the system, and the acidity drives CO2 out of the water. Equally, you can dissolved carbonate in water by adding CO2. So, it is not correct to use LeChatelier principle to explain the processes in the chain of reactions from CO2 dissolution to carbonate precipitations. Consider the reaction Ca2+ + 2 HCO3- CaCO3 + H2O + CO2(atm) . If you apply LeChatelier to this equation, then Carbonate precipitation will cause CO2 release into the atmosphere, not CO2 uptake from the atmosphere as explained in the video. So depending on how you formulate the process, LeChatelier considerations will give you different outcomes. Sorry, this is a brain twister and seems paradoxical. But LeChatelier is an approximation that only works on a simple single equilibrium equation, not a string of multiple equilibria. To memorize the effects of this complex system, it is best to think about alkalinity and pH: anything decreasing the pH of the water drives CO2 out of water, anything increasing pH will suck CO2 into the water.

I wish you could use a simple everyday language to describe it. like anime or something. when you use the technical words, many ordinary people will lost it. 😅. what is the relationship between CO2 and Alkalinity ? I am in Aquaculture.

This question is so vague that is impossible to answer. But in essence is the same. But you need to add all the fish 💩, algae formation, bacterial activity over rest of food…

At 9:50 you mean to say "carbonic acid", not "carboxylic acid". Given the other errors, suggest re-doing or removing this video, as it will create some confusion.
