Reversing ocean acidification is doable, if we have the political will | Opinion. Ocean acidification, one of many devastating effects of the warming earth, has been well-documented. We now know that this process is adversely affecting many of the species that are the cornerstone of major oceanic ecosystems.

There, carbon dioxide turns into carbonic acid. And that turns ocean water corrosive, particularly to shellfish and corals. Biologists are now coming to realize that rising acid levels in the ocean can affect many other forms of sea life as well. More CO2 in the ocean leads to it being acidified.”

The most effective way to limit ocean acidification is to act on climate change, implementing solutions to dramatically reduce the use of fossil fuels. If we dramatically cut our global warming emissions, and we limit future warming, we can significantly reduce the harm to marine ecosystems.

Ocean acidification reduces the amount of carbonate, a key building block in seawater. This makes it more difficult for marine organisms, such as coral and some plankton, to form their shells and skeletons, and existing shells may begin to dissolve.

Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. Currently, the burning of fossil fuels such as coal, oil and gas for human industry is one of the major causes. Deforestation results in fewer trees to absorb the gas.

Ocean acidification is occurring because too much carbon dioxide is being released into the atmosphere. Historically, carbon dioxide levels have been balanced; the CO2 being produced was in turn being absorbed. Deforestation not only creates more CO2, but it also destroys one of the very things that helps absorb it!

One of the major effects of ocean pollution is ocean acidification. Ocean acidification is caused by the ocean absorbing large amounts of carbon dioxide – almost 30 percent – in the atmosphere produced by the burning of fossil fuels and deforestation. Carbon dioxide is slightly acidic.

While previous estimates put the ocean sink at around 2bn tonnes of CO2 per year, we find that it could be 0.8-09bn tonnes larger. Over the whole 27-year study period of 1992-2018, this means the global oceans have taken up 67bn tonnes of CO2 rather than 43bn.

Today, average ocean pH is about 8.1. This might not seem like much of a difference, but the relationship between pH and acidity is not direct. Each decrease of one pH unit is a ten-fold increase in acidity.

Typical pH of Salt Water The average pH of the oceans near the surface is around 8.1. This means that the oceans are more alkaline than neutral. The pH of anything is usually a delicate balance.

Since adding salt to water does not result in any chemical reactions, the salt will not alter the pH level of water.

Sugar makes pH more acidic. The pH of your blood is tightly regulated and usually stays around 7.35 to 7.45. When experts talk about acidic or alkaline foods, they refer to your urinepH, since blood pH stays relatively stable.

No, salt (NaCl) is a neutral compound. That is it will have no effect on the pH of an aqueous solution. To make vinegar (acetic acid) more acidic you would have to increase its ability to ionize (acetic acid is a weak acid, as such it does not ionize completely in solution).
