-
- The acid with unknown concentration is slowly added from a burette into a conical flask that contains a volume of base with known concentration.
-
- Titration stopped when phenolphthalein changes from pink to colourless.
-
- Neutralisation is a reaction between an acid and an alkali (base) to produce salt and water only. In the reaction, the salt and water produced are neutral because the acid lose its acidity and the alkali lose its alkalinity
-
- In neutralisation, the hydroxide ions from the alkali combines with the hydrogen ions from the acid to produce water molecules.
-
- To determine the unknown concentration of an acid that needed to completely neutralise a given volume of alkali (vice versa)
-
- All the hydroxide ion in the base completely neutralize all the hydrogen ions in the acid to form water molecules.
-
-
-
- Measure the volume of acid and do numerical calculation to determine the concentration of acid
- Balance the chemical equation
- Find the number of moles for the solution of known concentration
- Compare the mole ratio
- Find the volume or concentration ( as per the question) using the mole ratio and formula.
- Phenolphthalein is pink in alkaline and colourless in neutral and acid.

- Antacid for gastric pain
- Production of fertilizer
