Solution.
"C(H2SO4) \\times V(H2SO4) = C(NaOH) \\times V(NaOH)"
C(H2SO4) = 0.125 * 2 = 0.25 mol-eq/dm3
"C(NaOH) = \\frac{0.25 \\times 0.0245}{0.025} = 0.245 \\ \\frac{mol-eq}{dm^3}"
C(NaOH) = 0.245 mol/dm3
Because the alkali equivalence factor is 1.
"C'(NaOH) = C(NaOH) \\times M(NaOH)"
C'(NaOH) = 9.80 g/dm3
Answer:
C'(NaOH) = 9.80 g/dm3
