Ocean Acidification
In this video Paul Andersen shows how carbon dioxide in the atmosphere is causing a decrease in the pH of the oceans. The carbon dioxide combines with the water to create carbonic acid which dissociates into bicarbonate and carbonate...

Why Is Carbon Dioxide Mixed In Cold Drinks And Beverages?
One of the most important factors when it comes to mixing any gas with a liquid is solubility, and carbon dioxide is highly soluble in water. In fact, it's the most soluble of the common, non-toxic gases with high solubility. To give you...
