Sea water is a solution of salt dissolved into water. as acidic, alkaline or neutral. Neutral solutions are exactly pH 7. Acidic solutions have pH values less than 7.

Reefs cover less than 1 percent of the ocean floor yet shelter about a quarter of all marine species and buffer shorelines ...

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.

The team repeated the same experiment without any worms; they just hooked up a pipe to the artificial tubes, and released a small squirt of sea water with a pH of 7.9—slightly more acidic than ...

Sea-urchin larvae, in contrast, have very basic, or alkaline, digestive juices — about 9.5 on the 14-point pH scale. Historically, ocean pH was about 8.16 on the pH scale, making it slightly ...

That compares to a global average of 8.1 on the logarithmic pH scale, ... "The Bering Sea is very acidic and the most acidic water in the global ocean, but it's not changing fast," he said.

In the past, the sea ice has kept the sea water close to the North Pole from being saturated with carbon dioxide. "The time-series of pH measurements made in the Arctic Ocean is long.

Neutralization reactions balance the acidity and alkalinity of solutions, forming salts and water. The pH scale is applicable in various fields such as medicine, environmental science, and biology.
