- Moles and Titration
- The more solute you dissolve in a given volume, the more crowded the solute molecules are and the more concentrated the solution
- Titrations allow you to find out exactly how much acid is needed to neutralise a solution
- Alkali in a flask with indicator (methyl orange) add the acid a bit at a tie giving the flask a regular swirl. Methyl orange turns yellow in alkalis and red in acids.
- Repeat the amount of acid used to neutralise the acid, take a mean of your results
- Calculating concentration
- Volume= moles x 1000 / Concentration
- Moles= volume x concentration / 1000
- Concentration= moles x 1000 / volume
