SUMMARY

A neutralization reaction between an acid and a base typically produces salt and water, exemplified by the formation of NaCl and H2O. However, when dealing with diprotic or multiprotic acids, such as sulfuric acid (H2SO4), and insufficient base, the reaction can yield an acidic salt, which retains a hydrogen proton. To determine whether a reaction produces an acidic salt or a regular salt, one must analyze the stoichiometry of the reactants, ensuring that less base is used than required for complete neutralization.

PREREQUISITES
  • Understanding of acid-base chemistry
  • Knowledge of diprotic and multiprotic acids
  • Familiarity with stoichiometry
  • Basic chemical reaction equations
NEXT STEPS
  • Study the properties of diprotic acids, focusing on sulfuric acid (H2SO4) and phosphoric acid (H3PO4)
  • Learn about stoichiometric calculations in acid-base reactions
  • Explore examples of acidic salts, such as sodium bisulfate (NaHSO4)
  • Investigate the role of pH in determining the nature of the salt produced
USEFUL FOR

Chemistry students, educators, and professionals in chemical engineering or laboratory settings who seek to deepen their understanding of acid-base reactions and the formation of acidic salts.

I understand that a neutralization reaction between an acid and a base will produce some type of salt (most commonly NaCl) and water (H2O).

However, I am now dealing with a neutralization reaction which produces an acidic salt (a salt with a hydrogen proton) and water.

I was wondering how this works, and how I would be able to tell which 2 acids & bases will produce this acidic salt.

Can you give an example of the reactant side of the formula, and explain how I could figure out from the reactants whether they will produce an acidic salt, or a regular salt?

Thank you.

Take any diprotic (or multiprotic) acid and add less base than is necessary for FULL neutralization.

It is all in stoichiometry.
