Test: The P-Block Elements 2 - From Past 28 Years Questions. Oxidation of antimony metal dominates in Europe. Also, using citric acid fuel with fuel to raw material ratio of 0.5, three primary solutions with three types of pH (acidic, basic, and neutral) were prepared and sol-gel combustion process was repeated. With other reducing agents such as sodium borohydride or lithium aluminium hydride, the unstable and very toxic gas stibine is produced. no it is an acidic oxide is. Chemistry. This shows that gradually a) The basic strength of the hydrides increases b) Bond energies of M-H bonds increases The choice of process depends on the composition of the ore and other factors. More the oxidation state of the central atom (metal) more is its acidity. sb2o3. Antimony(III) oxide also dissolves in concentrated mineral acids to give the corresponding salts, which hydrolyzes upon dilution with water. The most common glass electrode is the pH electrode.

[ COPMT1993] a) Gypsum and calcium dihydrogen phosphate b) Gypsum and calcium phosphate c) Gypsum and H3P4 Take Zigya Full and Sectional Test Series. Typical steps include mining, crushing and grinding of ore, sometimes followed by froth flotation and separation of the metal using pyrometallurgical processes (smelting or roasting) or in a few cases (e.g. The Questions and Samsonov, 1981, 2nd ed. SiO 2 is slightly acidic whereas P 2 O 3 and SO 2 are the anhydrides of the acids H 3 PO 3 and H 2 SO 3. community of Class 12. It is the most important commercial compound of antimony. Home JEE Chemistry Among Al2O3, SiO2, P2O3 and SO2 the correct order of acid strength is. It is the most important commercial compound of antimony. the answer is neutral, basic, acidic, acidic and i am not sure why . c. Give the formula of an amphoteric. It is expected that the chemical will become reactive as it becomes basic. The Sb-O distance is 197.7 pm and the O-Sb-O angle of 95.6°. A basic oxide is an oxide which when combined with water gives off a base. Which of the following is the most basic oxide?a)Sb2O3b)Bi2O3 [2006]c)SeO2d)Al2O3Correct answer is option 'B'. Antimonium oxide dissolve in concentrated hydrochloric acid, sulfuric acid, aqueous alkali and hot tartaric acid solution. Step 1. 1 answer.
