Hello!
To solve this problem we need to know the value of
pKa for HC₂H₃O₂ (Acetic Acid) which is
4,76. Now we can apply the
Henderson-Hasselbach equation, as follows (assuming that HC₂H₃O₂ concentration is 0,22M):
So, the pH for this buffer solution of HC₂H₃O₂ and KC₂H₃O₂ is
4,50Have a nice day!
HCl is a strong acid and KOH is a strong base. HCl dissociates to form H⁺ ions and Cl⁻ ions and KOH dissociates to give out K⁺ and OH⁻ ions.
When H⁺ and OH⁻ ions react they form H₂O molecules which are neutral.K⁺ ions and Cl⁻ ions form KCl salts.
the balanced equation for the reaction is as follows
HCl + KOH ----> KCl + H₂O
products are therefore KCl and H₂O
Ne is isoelectronic with Na+ ion.
