Acid and Base Titration Curves

Q. 1) You should check if the acetic acid concentration is what is stated on the bottle of food-grade acetic acid solution. This could be easily done by titrating known volume of the acetic acid soution with a base (sodium hydroxide) for which we know the concentration and detecting the end point with an indicator. Sodiumhydroxide neutralizes acetic acid: CH3COOH (aq) + NaOH (aq)  CH3COONa (aq) + H2O When the equivalentpoint is reached, the solution turns basic and phenolphthalene changes to pink. Write down some notes about titration:
