SUMMARY

The discussion centers on how acids affect the ionization of water, specifically through the introduction of hydronium ions (H3O+). When a strong acid is added to water, it increases the concentration of hydronium ions, which in turn lowers the pH of the solution. This process is explained using Le Chatelier's Principle, which describes how the equilibrium of water ionization shifts in response to the addition of H3O+ ions. The conversation emphasizes the fundamental relationship between acid addition and pH reduction.

PREREQUISITES
  • Understanding of acid-base chemistry
  • Familiarity with ionization concepts
  • Knowledge of Le Chatelier's Principle
  • Basic grasp of pH scale and its implications
NEXT STEPS
  • Study the effects of strong acids on pH levels in aqueous solutions
  • Research the principles of Le Chatelier's Principle in chemical equilibria
  • Explore the ionization of water and its equilibrium constant (Kw)
  • Learn about the role of hydronium ions in acid-base reactions
USEFUL FOR

Chemistry students, educators, and anyone interested in understanding acid-base interactions and their effects on water ionization.

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?
 
Chemistry news on Phys.org
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
