Free base and excess base

Could someone tell me the relationship between excess alkali and free alkali?
Reply #22010-06-08
The more base that is measured, the higher the free base level! ! !

I think excessive alkali refers to sodium salts of basic phenols. The free base refers to the amount of sodium hydroxide present in the phenoxide salt, that is, those excess hydroxide ions.
