Problem Solving Read CAREFULL each statement and report your answers: - Volume, and Percentage strength should be rounded off to two decimal places, - Weight, Normality should be rounded off to four decimal places 107. The USP requires that hydrochloric acid contain not less than 35 and not more than 38 % w/w HCI. You are about to assay a sample of HCI (MW=36.46g/mol; sp gr 1.18) following the procedure below: 1) Accurately weigh 4.0520 in glass-stoppered flask while containing 45mL of water 2) Add methyl red ts 3) Titrate with 0.9035N sodium hydroxide 4) After titration, it was found out that 44.15mL of volumetric solution used to bring the reaction to end point and 4.15mL volumetric solution used in blank titration a) What type of titration occur on the titration? b) What is the name of the salt form from the neutralization reaction c) Calculate the percentage composition of HCI in % w/w d) Does the sample conforms to the official requirements?
