	Sodium Bicarbonate and Sodium Carbonate
		Sodium hydrogen carbonate is the least soluble of the substances in the mixture (0.82 mol/L at 0°C, compared to 1.5 mol/L for NH, 5.5 mol/L for NH Cl, and 6.1 mol/L for NaCl).
		Sodium hydrogen carbonate is used in medicine (frequently as an antacid), as a leavening agent in baking (it is “baking soda”), and in the manufacture of sodium carbonate, Na “Baking powder” is a mixture composed mainly of NaHCO

	FAQ: What is soda ash, and what's it used for in dyeing?
		If you buy sodium carbonate without the extra water molecules, then store it for several years in humid conditions, it will absorb some water and appear to lose strength, when in fact it has merely 'bulked up' and needs to be used in larger volumes.
		The type of sodium carbonate used in washing soda is a decahydrate, so you need to use a lot more washing soda than you would anhydrous soda ash, perhaps three times as much - assuming that you are able to find pure unadulterated washing soda that is suitable for use in dyeing.
		Baking soda, or sodium bicarbonate, decomposes at sufficiently high temperatures to form sodium carbonate, so it is an ideal substitute for dyes that will be fixed by extensive steaming or baking.
