What is titration? Define it.
Answer (3)
If (S)-phenylalanine is the reactant and it undergoes two consecutive SN2 reactions to form phenyl lactic acid, the absolute configuration of phenyl lactic acid will be (S).
This is because SN2 reactions proceed with inversion of stereochemistry at the reaction center, meaning that the absolute configuration of the product is opposite to that of the reactant. Since (S)-phenylalanine has an S configuration at its chiral center, the two SN2 reactions will result in inversion of stereochemistry and the product, phenyl lactic acid, will also have an S configuration at its chiral center.
Therefore, the absolute configuration of phenyl lactic acid will be (S).

Titration is the slow adding of one solution of a known concentration (known as titrant), being added to the know volume of another solution where the concentration is unknown. The titrant is added until the unknown concentration of the second solution is neutralised by the titrant, which is often apparent via colour change from using an indicator.
Titration is a technique in chemistry to find the concentration of a solution with an unknown concentration by reacting it with a solution of known concentration. It involves precise measurement and calculation based on the volume of titrant added at the reaction's endpoint. The process is essential in various fields, including pharmaceuticals and environmental testing.
