SUMMARY

The net ionic equation for the reaction between hydrofluoric acid (HF) and potassium hydroxide (KOH) is HF + OH- = H2O + F-. This reaction occurs because HF is a weak acid that does not fully dissociate in water, while KOH is a strong base that completely dissociates. The potassium (K+) and fluoride (F-) ions act as spectator ions in this reaction.

PREREQUISITES
  • Understanding of weak and strong acids and bases
  • Knowledge of ionic dissociation in aqueous solutions
  • Familiarity with net ionic equations
  • Basic chemistry concepts related to acid-base reactions
NEXT STEPS
  • Study the properties of weak acids, focusing on hydrofluoric acid (HF)
  • Learn about strong bases, specifically potassium hydroxide (KOH)
  • Explore the concept of spectator ions in chemical reactions
  • Investigate the process of ionic dissociation in various solvents
USEFUL FOR

Chemistry students, educators, and anyone studying acid-base reactions and ionic equations will benefit from this discussion.

Homework Statement


The net ionic equation for the reaction between aqueous solutions of HF and KOH is___.

Homework Equations

The Attempt at a Solution



At first I thought it would simply be H+ + OH- = H2O, with the K and F ions as spectator ions.
But the answer is apparently HF + OH- = H2O + F-.

Is this because HF is a weak acid that doesn't dissociate completely in water?

Yes. KOH is a strong base, fully dissociated, HF is a weak acid, dissociated only partially.
 
Thanks Borek!
