-All alkalis have a pH greater than seven and hence can be detected with litmus paper (red litmus will turn blue on contact with an alkali).
-Moderately concentrated solutions (over 10-3 M) have a pH of 10 or greater. This means that they will turn phenolphthalein from colorless to pink.
-Concentrated solutions are caustic (causing chemical burns).
-Alkaline solutions are slippery or soapy to the touch, due to the saponification of the fatty acids on the surface of the skin.
-Alkalis are normally water soluble, although some like barium carbonate are only soluble when reacting with an acidic aqueous solution.
