Question

Sodium chloride and citric acid reaction

Answer 1

Both Sodium Chloride and Citric acid are white crystalline solids. NaCl is a neutral ionic compound that completely dissociates into Na+ and Cl- ions when dissolved in a polar solvent such as water. Citric acid is an organic compound, a tricarboxylic acid (three COOH groups) that partially ioinizes to a H+ and (Citrate)- ions in equilibrium with the un-ionized citric acid when dissolved in water.
The two substances can be MIXED together to form a mixture. However, they do not chemically react with each other.
NaCl + Citric Acid <==> Citric Acid + NaCl.
This mixture can be used as a saline buffer for biochemical reactions. However, there is no new chemical compounds formed when you mix NaCl with Citric Acid (for example, HCl and Sodium Citrate are NOT formed).
