What Volume of CO2 is Produced from H3PO4 and Na2CO3 Reaction?

Click For Summary

Discussion Overview

The discussion centers around the calculation of the volume of carbon dioxide (CO2) produced from the reaction between phosphoric acid (H3PO4) and sodium carbonate (Na2CO3). It involves aspects of stoichiometry, gas laws, and the ideal gas equation, with a specific focus on a homework problem.

Discussion Character

  • Homework-related, Mathematical reasoning, Technical explanation

Main Points Raised

  • One participant presents a homework problem involving the reaction of H3PO4 and Na2CO3, seeking to determine the volume of CO2 produced under specific conditions.
  • Another participant suggests starting with the reaction equation to understand the stoichiometry of the reaction.
  • A further reply advises writing the equations to determine the moles of CO2 produced and suggests using a gas equation, possibly the ideal gas equation, to calculate the volume at the given pressure.
  • There is a clarification regarding terminology, noting that the term "perfect gas equation" is commonly referred to as the "ideal gas equation" in English.
  • One participant humorously comments on the challenges of translating scientific terms accurately, mentioning differences in terminology related to gas properties.

Areas of Agreement / Disagreement

Participants generally agree on the need to use the ideal gas equation for the calculation, but there is no consensus on the specific steps to take or the details of the reaction equation.

Contextual Notes

There are limitations in the discussion regarding the completeness of the reaction equation and the assumptions made in applying the ideal gas law, which may affect the calculations.

Who May Find This Useful

This discussion may be useful for students or individuals interested in chemistry, particularly those studying gas laws, stoichiometry, or working on similar homework problems.

Start with the reaction equation.
 
Write the equations, see how many moles of CO2 will be produced, use some gas equation(maybe the perfect gas equation) to calculate how much volume that occupies at this pressure.

perfect gas equation

For the record - in English it is called the ideal gas equation.

Haha, true that. Translating things literally is bound to fail.
I also saw there's a difference in english, with perfect gases being these that do not change their cp and cv with temp/pressure.
