Three sources of error in acid-base titration
1. We notice the colour change of the solution due to presence of indicator at the end point (one extra drop from buret added to solution in conical flask after equivalence point) and not at the equivalence point (when number of moles of acid=number of moles of base).
2. Parallax error: When we take the reading of solution in the buret from an angle rather than looking straight at the lower meniscus in colourless solutions and upper meniscus in coloured solutions, this gives an error in the final calculation of the molarity of our acid.
3. Precision of the buret: Some burets may be less precise than others in giving the correct reading. This increases the uncertainty in measurement of volume of titrant used.

Acid / Base Titrations: Pre-Laboratory Assignment 1. Give at least two characteristics desirable in a primary standard. 2. Define equivalence point and ritration and point. Do these two points in a titration occur when the same volume of titrant has been added? Explain 3. A student standardized a NaOH solution using KHC.H.O.. Three different KHC&H.O. samples were dissolved in water and titrated with the same NaOH solution, each to a phenolphthalein end point. The pertinent reaction is: KHC H404 aq)...

need help with 5 and 6 6-8: Acid-Base Titration: Practice Titrations provide a method of quantitatively measuring the concentration of an unknown solution. In an acid-base titration, this is done by delivering a titrant of known concentration into an analyte of known Although in this case you know the concentration of both NaOH and HCI, this will give you practice in performing a titration and calculating the concentration of the analyte, which in this case is HCI. 1. Start Virtual...
