If the CO2 is not removed by boiling after the addition of HCL, how will this affect the amount of NaoH required to reach the bromophenol endpoint. Explain.
sample of amygdalin yields alpha hydroxyphenylacetic acid that consists of 70% of the R isomer and 30% of its enantiomer. What is the specific rotation of this mixture? The specific roation of pure (R)-alpha-hydroxyphenylacetic is -154.
A student wants to prepare a dilute solution of iron (III) solution, . The student is provided with a stock solution of 0.800 +/- 0.001 M and a 100.00 +/- 0.008 mL volume trick flask since the experiment trquires about 80 mL of the dilute iron (II..
If 10.0mL of a 3.00x10-1 M Fe(NO3)3 in 0.500M HNO3 solution is placed in a volumetric flask and then diluted to 50.0mL total volume, what will be the concentration of Fe+3
