Carbon Dioxide and Water: Lewis Base or Bronsted-Lowry Base?

Click For Summary

Discussion Overview

The discussion centers on whether water acts as a Lewis base or if carbon dioxide acts as a Bronsted-Lowry base in the reaction that forms carbonic acid. The scope includes theoretical interpretations of acid-base behavior in chemical reactions.

Discussion Character

  • Debate/contested, Conceptual clarification

Main Points Raised

  • One participant questions whether water donates a pair of electrons to carbon dioxide, suggesting it may act as a Lewis base.
  • Another participant proposes that carbon dioxide could be considered a Bronsted-Lowry base if it accepts a proton from water.
  • Some participants assert that a balanced equation indicates a Bronsted-Lowry reaction, specifically mentioning a 1:1 ratio and the production of substances like OH or H3O+.
  • One participant expresses doubt about carbon dioxide accepting a proton, challenging the Bronsted-Lowry classification.
  • There is a mention of ethylene diamine's reaction with sulfuric acid, questioning if it also follows a 1:1 ratio and produces OH- or H3O+, indicating variability in acid-base reactions.
  • A participant notes that while some claims about balanced equations are correct in certain cases, they cannot universally apply, highlighting the complexity of acid-base definitions.

Areas of Agreement / Disagreement

Participants express differing views on the classification of the reaction involving carbon dioxide and water, with no consensus reached on whether water acts as a Lewis base or if carbon dioxide acts as a Bronsted-Lowry base.

Contextual Notes

Some claims depend on specific definitions and interpretations of acid-base theory, and the discussion reveals limitations in applying general rules to all reactions.

In the reaction of carbon dioxide and water to form carbonic acid, does water act as a lewis base because it donates a pair of electrons to carbon dioxide or does carbon dioxide act as a Bronsted-Lowry base because it accepts a proton from water?

Thanks.

if the generic equation looks like this after its balanced, then its a bronsted lowry

(its balanced 1:1) and it makes a substance and something else, usually with OH or H3O+

if its not then it would look like this:

HX + XOH = H2O + Salt

Huh?

I don't think CO2 accepts a proton.

what I am trying to say is that a bronsted lowry equations is balanced 1:1 and usually produces either OH or H3O
 
What about ethylene diamine reaction with sulfuric acid? Still 1:1? Produces OH- or H3+?

While what you wrote is right in many cases, it can't serve as a basis for understanding, as it is also wrong in many cases.
