They are present, but they do not participate in the overall chemistry. C. NH3 To find the number of moles of KOH we multiply the molarity of KOH with the volume of KOH, notice how the liter unit cancels out: As the moles of KOH = moles of HI at the equivalence point, we have 4.2 moles of HI. The equation of reaction is: KOH (aq)+HCl (aq)KCl (aq)+H2O (l) K O H ( a q ) + H C l ( a q ) K C l ( a q ) + H 2 O ( l ) . HCl (aq) + NaOH(aq) H2O(l) + NaCl(aq) Since HCl and NaOH fully dissociate into their ion components, along with sodium chloride (NaCl), we can rewrite the equation as: H+ (aq) + Cl- (aq) + Na+ (aq) + OH- (aq) --> H2O (l) + Na+ (aq) + Cl- (aq) A. CH3OH D. NH3 Therefore: \[ HI\;(aq) + KOH\;(aq) \rightarrow H_2O\;(l) + KI\; (aq) \], H+(aq) + I-(aq) + K+(aq) + OH-(aq) --> H2O(l) + K+(aq) + I-(aq), H+(aq) + OH-(aq) --> H2O(l) (Final Answer).

The pH at the equivalence point for this titration will always be 7.0, note that this is true only for titrations of strong acid with strong base. Is NaCl(s)-->Na+(aq) + Cl-(aq) an electrolyte or non-electrolyte? These are the ions that appear on both sides of the ionic equation.If you are unsure if a compound is soluble when writing net ionic equations you should consult a solubility table for the compound._________________Important SkillsFinding Ionic Charge for Elements: https://youtu.be/M22YQ1hHhEYMemorizing Polyatomic Ions: https://youtu.be/vepxhM_bZqkDetermining Solubility: https://www.youtube.com/watch?v=5vZE9K9VaJIMore PracticeIntroduction to Net Ionic Equations: https://youtu.be/PXRH_IrN11YNet Ionic Equations Practice: https://youtu.be/hDsaJ2xI59w_________________General Steps:1. A. K(SO4)2 To find the volume of the solution of HI, we use the molarity of HI (3.4 M) and the fact that we have 4.2 moles of HI: By dividing by 3.4 mol HI / L on both sides, we get: We are left with X = 1.2 L. The answer is 1.2 L of 3.4 M HI required to reach the equivalence point with 2.1 L of 2.0 M KOH. In addition, the anion (negative ion) created from the dissociation of the acid combines with the cation (positive ion) created from the dissociation of the base to create a salt.
