Definition of Standard solutions
Check what you remember
Read the wording for your board, then hide it and explain Standard solutions in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
A series of known concentrations is prepared, each measured for absorbance, so the unknown can be compared with a curve built from them.
