Взаимодействие KBr и конц H2SO4 · 1. 2KBr + H2SO4 → K2SO4 + 2HBr · 2. 2KBr + 3H2SO4 → 2KHSO4 + Br2 + SO2 + 2H2O. KBr. 0.192 g. H3BO3. 0.052 g. SrCl2. 0.08 g. NaF. 0.006 g. Double distilled water ... other salts separately, combine and adjust the pH to 6.8 with NaOH or H2SO4 ... ... during reaction of alcohols with KI because H2SO4 oxidizes HI to I2. But why this does not happen when H2SO4 react with KBr? Also why H3PO4 not used with KBr? Feb 4, 2020 ... Answer: Potassium bromide react with sulfuric acid to produce potassium bisulfate, bromine, sulfur dioxide and water. ajustada: 2 KBr + 2 H2SO4. → Br2 + SO2 + K2SO4 + 2 H2O. b) Los moles de bromuro potásico utilizados son: n (KBr) = = ⋅. = −1. 119. 25 mol g g molesr masa. Since there is an equal number of each element in the reactants and products of 2KBr + 2H2SO4 = K2SO4 + Br2 + SO2 + 2H2O, the equation is balanced.
