Question

Amadeo quantitatively transferred a precise mass of potassium dichromate to a flask. He swirled the flask after filling the flask halfway with deion calibration mark. Then he diluted to the mark, adding water above the calibration mark. How would Amadeo's calculated K2Cr20 molarity compare to the actual value? Explain. (Hint: Write the generic calculation (no numbers needed) and show where and how the calculation is affected).

Please answer

Answer 1

Generally standard solutions are prepared using volumetric flasks of desired volumes such as 50mL, 100mL.....
