A calibration is performed with a standard solution of iron in water. Aniron solution in methyl ethyl ketone is analysed based on this calibrationfunction. Is it likely to yield an accurate result? or would the result be toohigh or too low? Explai..
Give two reasons why a 100% yield is not obtained in actual chemical manufacturing processes.
A 10.0 mL sample of vinegar, which is an aqueous solution of acetic acid, CH3COOH, requires 16.5 mL of a .500 M NaOH solution to reach the end point in a titration. what is the molarity of the acetic acid solution? CH3COOH(aq)+NaOH(aq)>NaCH3COO(aq..
