Of course,pure water have equal concentrations of H+ and OH-.
The equation for the dissociation of water is: H2O ↔ H+ + OH-
The dissociation equation of water (H₂O) shows its self-ionization into hydronium (H₃O⁺) and hydroxide ions (OH⁻): [ \text{H}_2\text{O} \rightleftharpoons \text{H}^+ + \text{OH}^- ] For methanol (CH₃OH), it does not dissociate in the same way as water. However, in a basic medium, it can participate in reactions where it donates a proton, but it does not produce ions like water does.
The dissociation equation for zinc fluoride (ZnF2) in water is: ZnF2 (s) → Zn2+ (aq) + 2F- (aq)
The dissociation of CaCl2.2H2O involves breaking the compound into its ions when dissolved in water. In this case, CaCl2.2H2O will dissociate into Ca2+, 2Cl-, and 2H2O molecules. The dissociation process is driven by the attraction between the ions and the polar water molecules, causing them to separate and form a solution.
The acid dissociation constant (Ka) for an acid dissolved in water is the equilibrium constant for the dissociation reaction of the acid into its ion components in water. It represents the extent of the acid's ionization in water.
Of course,pure water have equal concentrations of H+ and OH-.
The acid dissociation constant (Ka) for an acid dissolved in water is equal to the ratio of the concentration of the products (H+ and the conjugate base) over the concentration of the reactant (the acid). It represents the extent of dissociation of the acid in water.
Acids dissolve in water to produce H+ ions, while bases dissolve in water to produce OH- ions. This process is known as ionization or dissociation, and it is a key characteristic of acidic and basic solutions.
dissociation of acid in water: A + H2O <-> A- + H3O+ with dissociation constant Ka = [A-][H3O+]/[A][H2O] = [A-][H3O+]/[A]. dissociation of base in water: B + H2O <-> HB+ + OH- with dissociation constant Kb = [HB+][OH-]/[B][H2O] = [HB+][OH-]/[B] dissociation of water in itself: 2H2O <-> H3O+ + OH- with dissociation constant Kw = [H3O+][OH-]/[H2O]^2 = [H3O+][OH-] where [H2O] has been ommitted because it is a pure liquid. substituting relations for Ka and Kb into Kw gives: Kw = [H3O+][OH-] = (Ka[A]/[A-])(Kb[B]/[HB+]) = KaKb where [A] = [HB+] and [B] = [A-].
Dissociation of sodium chloride in water solution: NaCl -----------Na+ + Cl-
The equation for the dissociation of water is: H2O ↔ H+ + OH-
The balanced equation for the dissociation of water is: 2H2O (liquid) ⇌ 2H+ (aqueous) + O2- (aqueous)
Pure water has a natural Ph due to the rate of dissociation to H+ and OH- is equal to rate of association to form H2O. Pure water has no free ions.
The equilibrium constant for the dissociation of acetic acid in water is known as the acid dissociation constant (Ka) and is approximately 1.8 x 10-5.
If the concentration of H3O+ and OH- ions are equal, the solution is neutral with a pH of 7. This is because in neutral water, the concentration of H3O+ ions (from dissociation of water) is equal to the concentration of OH- ions.
