Question

125.0mL of a solution of HCLO3 of unknown concentration is titrated with a 3.2-M solution of NaOH. If it takes 88 mL OF NaOH 2 reach the endpoint, what is the concentration of the HCL03?

Answer 1

HClO3 + NaOH ==> NaClO3 + H2O

0.088 L NaOH x 3.2 mol/L = moles NaOH = moles HClO3

moles HClO3/0.125 L = molarity of HClO3 (do the math)
