Question
![4. Why do you determine a mass by difference?
You use this because it's typically more
accurate.
5. What are equivalence points and end points? How do they differ?
equivalence point- the point @ which stoichiometric
quantities are brought together, end point- the
the equivalence point is theoretical, when end poi
6. Why should the standardized NaOH solution be kept in a stoppered bottle?
pr
7. What is parallax? Why should you avoid it?
Parallax is the upperent displacement or the di
da
in direction of an object as seen
from two diffe
points.
са
It should be colded because it ca
errors
in volume measurements.
