1. In a vinegar analysis lab. 5.0 mL of vinegar (mass =4.97 g) was obtained from a bottle that read 5.0% acidity. During a typical titration reaction, it was determined that the vinegar required 36.25 mL of 0.10MNaOH to reach the endpoint (Note: the initial reading is 0.00 mL and the final reading is 36.25 mL.). HAC+NaOH→NaAC+H2O a) Calculate the \% acetic acid by weight. (MM acetic acid =60 g/mol ) b) Calculate the accuracy of vinegar analysis (Assume the true value is 5.00% )
