1. Theoretical basis It can be seen from the structural formula that the hydrogen (Na+) on CMC is very easy to dissociate in aqueous solution (generally exists in the form of sodium salt), so CMC exists in the form of anion in aqueous solution, that is, it has a negative charge and is amphoteric....Read more »
