Question

Write the balanced neutralization reaction that occurs between H2SO4 and KOH in aqueous solution. Phases are optional. neutralization reaction: Suppose 0.350 L of 0.490 M H2SO4 is mixed with 0.300 L of 0.200 M KOH . What concentration of sulfuric acid remains after neutralization?

Answer 1

H2 SOy + 2 KOH RiSOy t2H2O + Given; moles of HrSO4= mol 0.350K X 0.490 mcl (M = 0.1715 mcle moles of kOH =0.30OK X 0.200 mcl = 0.06 male Moles of He SOy Consumed half of the males of KcH 0.00 0.03 mele Moles of H2SOv lept = O.1715 0.03 2 0.1415 mole, no. of mcles 0,14IS male Concentiation volume (o.350+0.20) L = 0.218 mol/L = 0.218 M Conc"
