Zn: [Ar] 4s^2 3d^10, vacant orbital to accept a lone pair and form a new one, the number of ligand atoms bonded directly to the central metal ion, Complex ion with a coordination number of 2 has a _______ shape, Complex ion with a coordination number of 4 has a _______ shape, Complex ion with a coordination number of 6 has a _______ shape, A coordination number compound contains at lease one ________ and a _______ to balance the charge, H- hydride We begin by calculating the concentration of the sodium and sulfite ions. We convert the given pKa values to Ka values by Ka = 10^-pKa. Any strong acid dissociated ________ in water to yield another _____, Any strong base dissociates ________ in water to yield another ______, a solution that can resist pH change upon the addition of an acid or a base, An acid-base buffer usually consists of a, HF is a weak acid and dissociated _______ in water; naF is a salt and dissociates _______ in water, the amount of acid or base that can be aded before the pH begins to change significantly, the pH range over which the buffer is effective, Due to the leveling effect the shape of the titration curve involving a strong acid and a strong base depends only on the ________ of the acid and base, not on their ________, the number of moles of a strong base (acid) added equals the numbers of the analyte (theoretical not experimental value), an experimental result observed by the color change of the indicator added before the titration. b. K_2SO_4. Determine the [H+], pH, and pOH of a solution with an [OH-] of 9.9 x 10^-6 M at 25 C. [H+] = 1.0 x 10^-14/9.9 x 10^-6 = 1.0 x 10^-9 M. Determine the [H+], [OH-], and pOH of a solution with a pH of 12.41 at 25 C. Determine the [H+], [OH-], and pH of a solution with a pOH of 4.38 at 25 C. The Kw for water at 0 C is 0.12 x 10^-14. PH_3, Identify the compound as acid, basic, or neutral when dissolved in water. NH4ClO4. 1. NH 4 Cl is an acidic salt. The reaction between a strong base KOH and the strong acid HClO4 produces KClO4. The major use of ammonium chloride is in nitrogen-based fertilizers. Classify the compound given as a strong acid, weak acid, strong base, or weak base. acid and base. CH_3NH_2, Identify the compound as acid, basic, or neutral when dissolved in water. Why Walden's rule not applicable to small size cations. B > C > A c. C > A > B d.
