Question

Consider the following representation of oxy-acid, Hn1S2On2, (where S is central sulphur atom and n1 and n2 are natural numbers). If there are two possible oxy-acid of sulphur A and B contains ratio of n2:n1 are 2 and 4 respectively, then sum of oxidation state of 'S' atom in both oxy-acid will be :

Correct answer: 9 / FOR ANY OXYACID OF SULPHUR NUMBER OF H-ATOMS = 2; H2S2O4 (N2/N1 = 2, OXIDATION STATE OF S = +3) AND H2S2O8 (N2/N1 = 4, OXIDATION STATE OF S = +6). SUM OF OXIDATION STATES = 3 + 6 = 9. Step 1: Aluminum chloride (AlCl3) is a salt of a strong acid (HCl) and a weak base (Al(OH)3). Step 2: In aqueous solution, it undergoes highly favorable hydrolysis: AlCl3 + 3H2O -> Al(OH)3 + 3HCl. Step 3: Therefore, the primary hydrolysis product is the gelatinous precipitate of aluminum hydroxide, Al(OH)3, which corresponds to option (b).
