. Sometimes during titrations, when NaOH is added to a solution of HCl, the equivalence point is missed, evident by the bright pink colour of the phenolphthalein indicator (which turns pink in basic solutions). Under these circumstances, if theconcentration of HCl was experimentally determined to be 0.1034 M with a 3.45 % error from the actual value. Determine the actual concentration of HCl.
