		By this equation it is seen that the relationship between hydrogen ion and carbon dioxide gas is a direct one.
		The carbon dioxide gas produced can be captured in some visible way, such as a balloon, thereby providing a clear chemical activity link to hydrogen ion concentration and, thereby, pH.
		The required amount of sodium hydrogen carbonate was weighted out (for readers who do not have a balance, 8.4 grams is about 1 1/2 level teaspoons of sodium hydrogen carbonate) and loaded into each of five balloons.

	Patent 6,432,450 (Site not responding. Last check: 2007-11-05)
		The gas-evolving component consists of alkali hydrogen carbonate, alkali carbonate, and/or alkaline-earth carbonate particles which are coated with at least one further substance, particularly with a melt of polyethylene glycol 6000.
		It is advisable then, of course, to select coarse-grained alkaline components and for instance use a coarse-crystalline form of the granular sodium carbonate or sodium hydrogen carbonate, since such particles sink more rapidly, which produces a delayed effervescent effect from the bottom.
		It has been found to be advantageous in the case of sodium hydrogen carbonate to select a grain size distribution where the major sieve fraction is in the range between 0.1 and 0.4 mm, preferably to the extent of 50 to 85% and particularly preferably to the extent of 70 to 85%.

		Carbon dioxide is often a limiting factor in photosynthesis and we can increase the amount of hydrogen carbonate in the water in a number of different ways.
		Blackman states that water cannot be saturated with carbon dioxide by 'merely bubbling gas through it, even in a very long time; prolonged shaking of the water with a large volume of pure CO will, however, achieve this.' The CO saturated water can be diluted with water to get the appropriate dilution.
		Sodium hydrogen carbonate is not recommended for this purpose by McLean and Ivimey-Cook's Textbook of Practical Botany (1952).

	Caveman to Chemist Projects: Potash
		The carbonate ion, on the other hand, acts as a base in aqueous solution, that is, it absorbs hydrogen ions wherever it finds them.
		If there is lots of hydrogen ion (acidic solution) the hydrogen ion sticks to the carbonate ion and forms a new ion, the hydrogen carbonate ion, or bicarbonate ion.
		If there is not much hydrogen ion around, carbonate in effect steals a hydrogen ion from water, leaving a hydroxide ion behind and producing an alkaline solution.

		Thus, in the case of a uraniferous ore for example, the ore being attacked by a sodium carbonate and/or bicarbonate liquor, the solubilised uranium which is present in the liquor after the attack operation was usually precipitated in the form of sodium uranate.
		Accordingly, the precipitation medium was the source of production of hydrogen sulphide which is troublesome from the point of view of exploitation and from the environmental point of view, and gave rise to the danger of causing partial reduction of the Mo in the form of `molybdenum blue`.
