Acid, Base and Salt

Acids have the following chemical properties: Acid + Reactive Metal → Salt + Hydrogen gas Acid + Metal Carbonate → Salt + Water + Carbon Dioxide gas Acid + Base oxide → Salt + Water Acid + Alkali → Salt + Water

Physical Properties of Acids Acids have the following physical properties: Tastes sour Turns moist blue litmus to red pH value < 7 Can conduct electricity Corrosive Colour of Litmus in Acids Litmus can be used as acid/alkali indicator. Image below shows the colour of litmus paper when immerse in acid and alkali. The litmus turn … Read more

Basicity of Acids Basicity of an acid is the number of hydrogen ions which can be produced by one molecule of the acid. There are 3 common types of Basicity of an acid monoprotic diprotic triprotic Monoprotic Acids The monoprotics acids are the acids that produced 1 H+ ion from each acid molecule.Example[begin{gathered}HClxrightarrow{{{H_2}O}}{H^ + } … Read more

Acids Acids form a class of chemical substances which contain hydrogen ions in aqueous solution, H+ (aq), as the only positive ion. Acids are usually classified into mineral or organic acids. Mineral Acids generally much stronger most do not occur naturally usually have simpler molecules Example Sulphuric Acid Nitric Acid Hydrochloric Acid Phoshoric Acid Carbonic … Read more
