When a 0.5725 g sample of Lysol was titrated with 0.100 M NaOH, and endpoint was obtained at 15.00 mL. What is the percent of HCL in the lysol sample?

Answer 1

Technically, there may not be ANY HCl in the Lysol but you may calculate the acidity in terms of the HCl content.

moles NaOH = M x L = ??
moles HCl = same thing since 1 mole NaOH exactly neutralizes 1 mole HCl.
g HCl = moles HCl x molar mass HCl.

%HCl = (mass HCl/mass sample)&100 = ??

Answer 2

9.55%
