Carbon dioxide phase diagram. Supercritical carbon dioxide blend (sCO 2 blend) is an homogeneous mixture of CO 2 with one or more fluids (dopant fluid) where it is held at or above its critical temperature and critical pressure. [1]
It works by releasing carbon dioxide gas into a batter or dough through an acid–base reaction, causing bubbles in the wet mixture to expand and thus leavening the mixture. The first single-acting baking powder (meaning that it releases all of its carbon dioxide as soon as it is dampened) was developed by food manufacturer Alfred Bird in ...
If the carbon dioxide content is lower than 0.04%, it changes from red to magenta and, in relatively very low carbon dioxide concentrations, to purple. [1] Carbon dioxide, even in the concentrations found in exhaled air, will dissolve in the indicator to form carbonic acid , a weak acid , which will lower the pH and give the characteristic ...
Soda lime canister used in anaesthetic machines to act as a carbon dioxide scrubber. Soda lime, a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO), is used in granular form within recirculating breathing environments like general anesthesia and its breathing circuit, submarines, rebreathers, and hyperbaric chambers and underwater habitats.
A soda geyser is a physical reaction between a carbonated beverage, usually Diet Coke, and Mentos mints that causes the beverage to be expelled from its container. The candies catalyze the release of gas from the beverage, which creates an eruption that pushes most of the liquid up and out of the bottle.

Paul Sabatier (1854-1941) winner of the Nobel Prize in Chemistry in 1912 and discoverer of the reaction in 1897. The Sabatier reaction or Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures (perhaps 3 MPa [1]) in the presence of a nickel catalyst.
Carbogen, also called Meduna's Mixture after its inventor Ladislas Meduna, is a mixture of carbon dioxide and oxygen gas. Meduna's original formula was 30% CO 2 and 70% oxygen, but the term carbogen can refer to any mixture of these two gases, from 1.5% [ 1 ] to 50% [ 2 ] CO 2 .
