Acidity is measured on the pH scale , a scale of numbers normally ranging from 0 to 14. A pH value of 7 is neutral, less than 7 is acidic and more than 7 is alkaline. A universal indicator gives different colours corresponding to different pH values, typical results being red for pH ...

Bases Bases arebitterin taste andsoapyto touch. Ifhydroxylions are found in a solution, the solution is basic in nature. Hydroxyl ions are the only negatively-charged ions (anions) formed when a base dissolves in water. All the properties of a base are due to the presence of these ions....
- Add acid and slowly stir until colourless - Repet multiple times for accuracy - Evaporate the water from the solution How are names of salts formed? The name of the salt begins with the name of the metal, followed by the name reflecting the acid it was made from e.g. Sodium Chloride...
