SUMMARY

The discussion focuses on determining the percentage of glycolic acid required to replace a 40% solution of phosphoric acid by weight. The initial calculation involves converting the weight percentage of phosphoric acid to molarity, yielding a concentration of 5.11 mol/L. Given that phosphoric acid is triprotic, the molarity of glycolic acid must be calculated by multiplying the phosphoric acid molarity by three. This method establishes a clear pathway to find the required glycolic acid concentration.

PREREQUISITES
  • Understanding of weight percentage and molarity conversions
  • Knowledge of triprotic acids and their dissociation
  • Familiarity with glycolic acid and phosphoric acid properties
  • Basic skills in chemical calculations and stoichiometry
NEXT STEPS
  • Calculate the molarity of glycolic acid needed to achieve equivalent acidity
  • Research the properties and applications of glycolic acid in chemical reactions
  • Explore the concept of acid-base neutralization and its calculations
  • Examine the implications of using glycolic acid as a substitute for phosphoric acid in various applications
USEFUL FOR

Chemistry students, chemical engineers, and professionals involved in acid-base chemistry or formulation of chemical solutions.

Homework Statement


What is the % glycolic acid needed to replace 40% phosphoric acid (assuming it is weight%)?

Homework Equations

The Attempt at a Solution


I tried to solve this by first converting the Phosphoric acid weight% to mol/L for the phosphoric acid (5.11 mol/L)..
Since phosphoric acid is triprotic, I just multiply by 3 the calculated Molarity of phosphoric acid for the molarity of glycolic acid ... I am not sure if i did it right...how do we find the answer?
