Feb 26, 2023 ... 3H2SO4(конц.) + 2KBr(тв) = SO2↑ + Br2 + 2H2O + 2KHSO4 SO4(2-) + 4H(+) + 2e- → SO2 + 2H2O |1 2Br(-) - 2e- → Br2 |1 SO4(2-) + 4H(+) + 2Br(-) ... Apr 12, 2024 ... We swirled the mixture so that the concentrated H2SO4 mixed with the KBr solution then noted the color of the dichloromethane layer. ... KI + KBr ... H2SO4 +2 KBr + 2 H+ → 2K+ +Br2 + SO2 + 2 H2O. 2 H2SO4 +2 KBr → K2SO4 +Br2 + SO2 + 2 H2O (Ecuación molecular) b). 2 H2SO4 +2 KBr → K2SO4 +Br2 + SO2 + 2 H2O. Oct 11, 2020 ... You must mix the ascorbic acid powder sample with 1.5 M H2SO4 and KBr. What role do these reagents play in this initial mixing? 5.95g of potassium bromide (KBr) was dissolved in water, and make a 400 mL solution. ... mol H2SO4 = molarity H2SO4 x volume of H2SO4 in L mol H2SO4 = 0.800 x 250 ... 2 AlBr3 + 3 K2SO4 → 6 KBr + 1 Al2(SO4)3. 7). 1 CH4 + 2 O2 → 1 CO2 + 2 H2O. 8). 1 C3H8 + 5 O2 → 3 CO2 + 4 H2O. 9). 2 ... 1 H2SO4 + 2 NaNO2 → 2 HNO2 + 1 Na2SO4.
