Question- A student raises the plastic weighing boat but throws this rinse water down in the sink instead of adding it to the volutmetric flask.
1) How would the readings from the spectrophotometer change (higher, lower or unchanged)
2) Explain how this will affect the calculation of the amount of glucose in the in known sample will it be too high, too low, or unchanged? Explain your answer.
If possible just a brief explanation how you got the answer?
An unknown sample of Cu2+ gave an absorbance of 0.292 in an atomic absorption analysis. Then 2.00 mL of solution containing 100.0 ppm (= µg/mL) Cu2+ was mixed with 95.0 mL of unknown, and the mixture was diluted to 100.0 mL in a volumetric flask. ..
