- Acids and Alkalis!
- The strongest acids have a pH of 0
- The strongest alkali has a pH of 14
- pH Scale:
- Acids and Alkalis!
- it measures how acidic or how alkaline a solution is.
- pH Scale:
- pH Scale:
- A neutral substance has a pH of 7 for example pure water!
- The pH scale measures from 0-14
- You use a indicator to estimate the pH of a solution
- An acid is something with a pH lower than 7
- The strongest acids have a pH of 0
- The strongest alkali has a pH of 14
- A base for an acid would have to have a pH over 7
- The strongest acids have a pH of 0
- A base and a acid neutralise one another
- A base for an acid would have to have a pH over 7
- An alkali is a base that can dissolve in water
- The reaction between acids and bases are called neutralisation
- Acid + base ----> salt + water
- A base and a acid neutralise one another
- A base and a acid neutralise one another
- In a equation there are (s), (l),(g) and (aq)
- These mean (s) - solid. (l) - liquid. (g) - gas. (aq) - aqueous (dissolved in water).
- In a equation there are (s), (l),(g) and (aq)
