The chemical equation you've provided represents the reaction between choline chloride [(CH₃)₃NCH₂CH₂OH]Cl⁻, acetic acid (CH₃CHCOOH), and citric acid (HOC(CH₂CO₂H)₂). Here's the balanced equation for the reaction:
In this reaction, choline chloride reacts with acetic acid and citric acid to form a product in which the choline chloride molecule is esterified by one of the carboxylic acid groups of citric acid. The balanced equation indicates the formation of the ester [(CH₃)₃NCH₂CH₂OC(CH₂CO₂H)₂]Cl⁻, water (H₂O), and hydrochloric acid (HCl) as products.
