Errors in standard dilution

Question

What are some errors that could occur when making a standard dilution and when plotting a calibration curve?

What about errors using a spectrophotometer?

Thank you

Answer 1

The most common error made in standard dilutions is pipetting errors. Other errors include calculation errors and bad technique in transferring solutions from place to place.

Errors in "plotting" a calibration curve arise from errors in making the dilutions and not in the actual "plotting" of the curve. This is an ambiguous question.

Errors using a spectrophotometer may arise from an incorrect "blank", using unclean equipment (cuvettes, etc.), using an incorrect wavelength, etc.
