Base (chemistry) Base (chemistry) In chemistry, bases are substances that, in aqueous solution, release hydroxide (OH) ions, are slippery to the touch, can taste bitter if an alkali, change the color of indicators (e.g., turn red litmus paper blue), react with acids to form salts, promote certain chemical reactions (base catalysis), accept protons from any proton donor or contain completely or partially displaceable OH ions. Examples of bases are the hydroxides of the alkali metals and the alkaline earth metals (NaOH, Ca(OH), etc., see alkali hydroxide and alkaline earth hydroxide). These particular substances produce hydroxide ions (OH) in aqueous solutions, and are
The 10% Solution for a Healthy Life to forty percent of caloric intake is from fat. Numerous agencies such as the American Dietetic Association, American Heart Association and U.S. Surgeon General advocate thirty percent of caloric intake from fat. However, Kurzweil says this causes a comparatively slight reduction in atherosclerosis levels.
