Citric Acid and Sodium Hydroxide

C6H8O7 + 3NaOH → Na3C6H5O7 + 3H2O

개요

Citric acid is a triprotic acid that reacts with three equivalents of NaOH to form trisodium citrate and water. The three pKa values (3.13, 4.76, 6.40) create a broad buffering range. Sodium citrate is an important anticoagulant and food additive.
