A group of students is doing an analysis of copper in a 1-peso coin. They were tasked to prepare standard solutions and weigh the analyte as the end-product of their experiment. What type of error is it and explain how this type of error incurring in their experiment. a. Makisig forgot to calibrate the analytical balance before weighing. b. Only one trial was performed in the experiment. c. One member inadvertently recorded 29.90 mL instead of 19.90 mL volume. d. Marikit had very good precision but
A group of students is doing an analysis of copper in a 1-peso coin. They were tasked to prepare standard solutions and weigh the analyte as the end-product of their experiment. What type of error is it and explain how this type of error incurring in their experiment.
a. Makisig forgot to calibrate the analytical balance before weighing.
b. Only one trial was performed in the experiment.
c. One member inadvertently recorded 29.90 mL instead of 19.90 mL volume.
d. Marikit had very good precision but poor accuracy in her data.
e. Volumetric flasks were placed inside the oven for drying before it was used.
f. Trial 1 and 2 have values close to 30.0 mL while trial 3 gave 55.0 mL.
g. The reagent used in determining copper was added incorrectly and gave a low yield.
