In this lab, the hydrochloric acid solution was the because its concentration was not known. However, the sodium hydroxide solution in the buret was the because its concentration was known.
However, the sodium hydroxide solution in the buret was the solventanalyte✔ titrant
During this lab, you used a buret to add analyte to the flask and to add titrant to the analyte. Why is a buret a better tool for adding liquid in this experiment than, say, a graduated cylinder?
A buret allows more precise volume measurements and lets you control the flow of liquid drop by drop with its stopcock. It can also be clamped securely, which helps prevent spills.
Suppose a student added NaOH solution from the buret drop by drop until reaching the equilibrium point. Instead of closing the stopcock, he mistakenly opened it wide but then immediately switched it off. Check all the possible effects.
Suppose that Max and Maria recorded data from the same buret. Their data are shown to the right. What is the most obvious error that Max made?
Food scientists apply principles of titrations to food testing and develop foods that meet certain food-safety standards. For example, the acidity of milk increases with time, making it sour. Which statements make sense? Check all that apply.
