Answer 2

Equation and Name of the Salt Formed from the Reaction of Oleic Acid with Potassium Hydroxide

The equation for the reaction between oleic acid (C18H34O2) and potassium hydroxide (KOH) can be written as follows:

C18H34O2 + KOH → K(C18H33O2) + H2O

The salt formed from this reaction is called potassium oleate (K(C18H33O2)) [[1]].

Molecular and Ion-Molecular Equations for the Reactions

a) Reaction between Potassium Palmitate and Water:

The molecular equation for the reaction between potassium palmitate (C15H31COOK) and water (H2O) can be written as:

C15H31COOK + H2O → C15H31COOH + KOH

The ion-molecular equation for the reaction can be written as:

C15H31COO^- (aq) + H2O (l) → C15H31COOH (aq) + OH^- (aq)

b) Reaction between Magnesium Stearate (Insoluble Salt) and Hydrochloric Acid:

The molecular equation for the reaction between magnesium stearate (Mg(C18H35O2)2) and hydrochloric acid (HCl) can be written as:

Mg(C18H35O2)2 + 2HCl → 2C18H35COOH + MgCl2

The ion-molecular equation for the reaction can be written as:

Mg(C18H35O2)2 (s) + 2H^+ (aq) + 2Cl^- (aq) → 2C18H35COOH (aq) + Mg^2+ (aq) + 2Cl^- (aq)

Please note that the reaction between magnesium stearate and hydrochloric acid forms a precipitate of magnesium chloride (MgCl2) due to the insolubility of magnesium stearate in water [[2]].
