Concept Introduction:-
Standard additions to one solution:
The graph can be drawn using the equation
Where X-intercept is
Confidence Intervals:
The confidence interval is given by the equation:
Where,
n is number of measurements
The concentration of original unknown is
b)
Interpretation:
The criticism of this experiment is that too much added standard creates error because the standards contribute too much to the computed result and reading from the initial solution was not weighted heavily enough has to be explained.
