mols NaOH = M x L = ?
mols HClO4 = mols NaOH (from the coefficients in the balanced equation)
M HClO4 = mols/L solution.
A 20.00−mL sample of an unknown HClO 4 solution requires titration with 22.92mL of 0.2200M NaOH to reach the equivalence point.
What is the concentration of the unknown HClO 4 solution? The neutralization reaction is:
HClO 4 (aq)+NaOH(aq)�¨H 2 O(l)+NaClO 4 (aq)
