Suppose your laboratory instructor inadvertently gave you a sample of khp that was contaminated with nacl to standardize your naoh how would this affect the normality you calculated for your naoh sol?
Potassium acid phthalate is a common primary standard used to standardize bases. Obviously, it would depend upon how much NaCl was present, but the end result will be to reduce the amount of available H+ for the mass of KHP-NaCl mixture. That would cause you to understate the concentration of the base.

How can you calculate standard error in volume?
The standard error is calculated by dividing the actual volume by the experimental volume. This is a common technique used in the laboratory.
How does the binomial nomenclature prevent confusion in biology?
Early scientific names were often very long and hard to standardize. Names produced by binomial nomenclature are only two words long and hold more closely to a common standard.
