The salt formed from a reaction between citric acid and sodium hydroxide in solution will be?
A
acidic
B
basic
C
complex
D
neutral
Verified Correct Answer: B.
Chemical Principles & Mechanism
Citric acid has 3 carboxyl groups, therefore, when reacts with NaOH, there is a simple salification reaction that will produce the trisodium citrate / sodium citrate.
Trisodium citrate is a tribasic salt of citric acid. It is produced by complete neutralization of citric acid with high purity sodium hydroxide or carbonate and subsequent crystallization and dehydration.
