This video gives an overview of how increasing carbon dioxide dissolved in ocean water creates a more acidic environment. Questions addressed in the video are what chemical processes are involved due to the presence of dissolved carbon dioxide, in particular how does increased dissolved CO2 affect those processes, and how does an increase in dissolved carbon dioxide affect marine life?

Hello, I have read about this in a paper titled "Anthropogenic ocean acidification over the twenty-first century and its impact on calcifying organisms," and that paper, from 2005, suggested that shell degradation would start occurring in 2050, in the southern ocean and then spread globally, if the human carbon footprint stays in a "business as usual" state. The human carbon input to the atmosphere in 2005 was less than 8 gigatons annually. In 2023 the human carbon input is greater than 10 gigatons annually. That is an increase versus static, or "business as usual." My greatest concern is oxygen depletion in the atmosphere due to shell degradation in phytoplankton. Phytoplankton are calcifying organisms that, among other marine organisms, provide a significant amount of the oxygen that we breathe. Phytoplankton are also at the base of the marine food web. Additionally, any solutions would have to be applied at a similar rate as the pollution that is being applied to the atmosphere. For example, applying lye, iron, seaweed, or any other solution would have occur at a similar rate to the pollution that is entering the atmosphere. In 2022, globally, there were 100 million barrels (42 gallons each) of oil consumed each day. Imagine even a fraction of that, 1 million barrels a day, of lye, iron, seaweed, or something else being applied to the ocean, for many years. Should we halt the pollution or should we keep polluting and hope for a technological miracle?

It takes about 40 years for the burning of carbon fuels to soak the oceans and the result of our actions over the last 150 years is that we have a huge carbon battery in the oceans. We are at 400 ppm atmospheric co2 for the next 1000 years. Plant more plants on land and reestablish eelgrass in our coastal waters.

why isn't H+ becoming H3O+ when it dissolves in water ?
@CrashChemistryAcademy
@CrashChemistryAcademy 7 месяцев назад
Yes, All aqueous H+ ions exist as H3O+. For acid-base chemistry, aqueous H+ is used as a shorthand for H3O+. In particular showing it as aqueous H+ does not change the overall reaction since H3O+ will have H2O present on both sides of the equation and so can be ignored- leaving out the H2O as if writing a net equation.
