Phenol plus chcl3 and naoh
WebThe best way to do this reaction is bubbling CH 3 Br gas into the aqueous NaOH solution. Reaction with physical states CH 3 Br (g) + NaOH (aq) → CH 3 OH (aq) + NaBr (aq) Except CH 3 Br, all other compounds are soluble in water. Aqueous sodium hydroxide is prepared by dissolving NaOH crystals in water. Safety during the reaction WebMalonic acid (HO2CCH2CO2H) is a diprotic acid. In the titration of malonic acid w ith NaOH, stoichiometric points occur at pH = 3.9 and 8.8. A 25.00-mL sample of malonic acid of unknown concentration is titrated with 0.0984 M NaOH, requiring 31.50 mL of the NaOH solution to reach the phenolphthalein end point.
