Cambridge International AS and A Level Chemistry by Ryan Lawrie, Roger Norris
Alkali Notes:
An alkali is an aqueous solution with a pH value of more than 7. Alkali is the synonym of base. We can say that an alkali is a base that dissolves in water. Alkali are one of the most common bases. Alkali turn phenolphthalein from colourless to pink as they have pH greater than 7. Alkaline solutions are slippery and soapy to the touch. They can cause chemical burns as their concentration solutions are known to be caustic. Examples of alkali include, sodium hydroxide, potassium hydroxide, magnesium hydroxide etc. Alkali are also very useful and have great importance in chemistry. Sodium hydroxide is used in the manufacture of paper, detergents and soap. Alkali can also be used in farming as potassium hydroxide is used to make acidic soil more alkaline so that plants can grow better in it. It can also be used as electrolyte in batteries.
