Question

- US moi total volume = lomL + 15 m2 = 25 mL pH =- Log [ht] =number of md/ Volume - 0.5 mmol / 25 ML 1. -0.am 11. Indicate each of the following aqueous solutions is acidic, basic, or neutral: KF =-Log HI КОН 12. A metal complex is Cr(H20)2Br4. (25 pt) a) Name the complex. b) Give formulas of ligands. c) What is charge of Cr? mumhor of the complex.

Answer 1

Soln:- Son T KF 4 It is made up of KOH and HF a Strong Base weak Acid Hence; aqueous solution of kf is Basic in Nature KI It is made up of KOH + HI Strong Base Strong Acid; Hence; Aqueous solution is Necebal in nature. kon HI Basic Acidic (strong Base) ( stoong Acid)

127. Grillen Metal complex is (o (H20), Brg- Hence; It is Ion Negative part of the complex compound. A ligands present H2o, Br H2O + neutral ligand (Aquol Br + negative ligand ( Bromo) central Atom = chromium (Cr) Rule & But when used as Negative part then chromium & choomate let charge of central atom (Co) be a 370-4=-1; 701 = t3 | Hence; Name of the complex diaquo tetoa Bromo chromate (II) Formulas of ligand: Hot Aqua ; Br Bromo charge of co = t3 .
