Example: A 200 ml cell contains initially about 100 grams of sodium chlorate (the solubility of NaClO3 in water is about 50 g/100ml at room temperature). Sodium perchlorate is conveniently converted in high yield to a number of other perchlorates (such as potassium and ammonium perchlorate) by double decomposition (metathesis) reactions. As a rule of thumb maintain a current density of 200 mA/cm2. It hydrolysis reaction is below, 5.1A Strongly oxidizing hazardous materials, UN 1447 , 5.1 (6.1), II, Segregation Group: 13 (Perchlorates), Substances not precipitated by sulfuric acid (as sulfates). The equation for Ba(ClO4)2 is:HClO4 + Ba(OH)2 = Ba(ClO4)2 + H2OIt is also useful to have memorized the common strong acids and bases to determine whether Ba(ClO4)2 acts as an acid or base in water (or if it forms a neutral solution).Strong acids: HCl, H2SO4, HNO3, HBr, HI, HClO4Weak acids: HF, CH3COOH, H2CO3, H3PO4, HNO2, H2SO3Strong Bases: LiOH, NaOH, KOH, Ca(OH)2, Sr(OH)2, Ba(OH)2Weak Bases: NH3, NH4OHNote that we are talking about whether Ba(ClO4)2 is an acid, base, or neutral when dissolved in water.- Salts of strong bases and strong acids: pH will remain neutral at 7.- Salts of weak bases and strong acids: pH less than 7 (acidic).- Salts from strong bases and weak acids: pH greater than 7 (alkaline).Based on these rules, the solution of Ba(ClO4)2 dissolved in water is neutral.For polyprotic acids (e.g. Clear All Catalogs and product finders.
