More on Acids and Alkalis

Acids and alkalis are 2 different types of solutions. Below shows some of the properties of acids and alkalis.

ACIDS
- neutralise alkalis
- turn litmus paper from blue to red
- produces hydrogen gas when mixed with certain metals
- produces carbon dioxide gas when mixed with carbonates
- are good electrical conductors
- have a sour taste
- weak acids can be consumed
- examples: citric acid, ethanoic acid, hydrochloric acid, sulphuric acid, nitric acid, phosphoric acid

ALKALIS
- have a slippery feel
- turn litmus paper from red to blue
- have a bitter taste
- are good electrical conductors
- neutralise acids
- react with ammonium salts to produce ammonia gas
- examples: sodium hydroxide, calcium hydroxide, beryllium hydroxide, calcium oxide, magnesium hydroxide, potassium hydroxide, ammonia solution
