Click For Summary

Discussion Overview

The discussion revolves around how acids affect the ionization of water, particularly focusing on the relationship between acid addition and the concentration of hydronium and hydroxide ions in solution. The scope includes basic theoretical concepts and applications of chemical principles such as Le Chatelier's Principle.

Discussion Character

  • Conceptual clarification
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant asks how acid affects the ionization of water, specifically regarding the presence of hydroxium ions.
  • Another participant asserts that adding a strong acid to water will increase the concentration of hydronium ions, thus lowering the pH.
  • A third participant emphasizes that adding acid to any solution will lower the pH, regardless of the initial conditions, and suggests considering Le Chatelier's Principle in relation to the equilibrium of water ionization.
  • A later reply confirms the idea of lowering the pH when acid is added.

Areas of Agreement / Disagreement

Participants generally agree that adding acid lowers the pH and increases hydronium ion concentration, but there is some contention regarding the clarity of the initial question and the application of chemical principles like Le Chatelier's Principle.

Contextual Notes

The discussion does not resolve the implications of Le Chatelier's Principle on the equilibrium of water ionization, nor does it clarify the specific conditions under which these changes occur.

i need some helps...how does acid affect the ionization of water ?

...how does acid affect the ionization of water ?
if there are more hydroximum ions in the solution,what will the change of ionization of water?

This is a very basic question...why don't you read your text? Assuming a strong acid/water solution for instance, the acid will protonate the water raising the concentration of hydronium relative to hydroxide, thus raising the pH.
 
Yes. Very basic question. PLease consult your notes or textbook. When you add acid to "anything" (buffer solution, basic solution, neutral solution, acidic solution), it will lower the pH, even a tiny amount.

(GCT ---> don't you mean: "...thus lowering the pH")

I think that you may also be thinking about Le Chatelier's Principle here
2H2O --> H3O + OH
let's say you add H3O ions that are provided by the acid
how does that shift the equilibrium? use your knowledge of Le Chatelier's Principle.
 
yes, lowering the pH
