NaAlo2 + Naoh
What is the purpose of adding NaOH to the mixture before taking the polarimeter reading?
It is to neutralize the solution and to stop the hydrolysis.
Why is NaOH added to water and not the other way?
To keep your eyebrows intact. Adding water into NaOH will generate hellaheat.
Is adding NaOH to HCL chemical or physical change?
It is a chemical change. NaCl + H2O
Why is it necessary to standardize the NaOH solution before titration?
It allows the concentration of the NaOH to be known.

Why is the NaOH extract heated before acidification?
To remove any remaining traces of another existing compound that might inhibit the crystallization of the phenol.
Why is NaOH added to water and not the other way?
To keep your eyebrows intact. Adding water into NaOH will generate hellaheat.
Purpose of adding NaOH to the mixture before taking the polarimeter reading?
To neutralize the solution and to prevent the complete hydrolysis of sucrose into glucose and fructose.
What happens to sodium hydroxide when heated?
At very high temperature NaOH is decomposed and Na2O fumes are emited.The reaction is:2 NaOH = Na2O = H2O
What are the functions of NaOH in benzoylation of amine?
in benzoylation of amine, HCl is produced which by adding NaOH, HCl consumed and the raction proceed for production of further benzoylation product.
