- Part 2b A Student Transfers 25 00 Ml Of Hcl With A Graduated Cylinder To An Erlenmeyer Flask Adds Phenolphthalein And 1 (105.01 KiB) Viewed 25 times
Part 2b: A student transfers 25.00 mL of HCl with a graduated cylinder to an Erlenmeyer flask, adds phenolphthalein, and titrates with NaOH (0.1000 ± 0.0004M) using a buret, to the endpoint, which requires 30.9 mL of NaOH. (The student only reports value of titrant to one decimal place) Volume of HC1 = 25.00 mL + Molarity of NaOH = 0.1000 M + Volume NaOH = 30.9 mL ± Moles NaOH = Moles HC1 Molarity HC1 = = Relative uncertainty (%) ++ ± ± +1
