Identify if the below errors are human, random, or systematic. Indicate if they would affect the accuracy, precision, or percent yield of the experiment. Zelda titrated to a bright pink color when using phenolphthalein indicator. Aaray did not let his aspirin product fully dry in the vacuum filtration before weighing it. When doing a density experiment, the temperature of the room slowly increased, causing the temperature of the water to increase unknowingly. Fatima only measured the water temperature at the start of the experiment.

Question
**Experimental Errors** - Identify if the below errors are human, random, or systematic. Indicate if they would affect the accuracy, precision, or percent yield of the experiment. 1. Zelda titrated to a bright pink color when using phenolphthalein indicator. 2. Aray did not let his aspirin product fully dry in the vacuum filtration before weighing it. 3. When doing a density experiment, the temperature of the room slowly increased, causing the temperature of the water to increase unknowingly. Fatima only measured the water temperature at the start of the experiment. 4. The concentration on the bottle of NaOH used in Omar’s titration was marked as 0.200 M. It was actually 0.215 M, but this was not known. 5. The air conditioner in the room cycled on and off throughout the lab period. This caused a draft at the balance station when Kayden was weighing their reactant.

Expert Solution
Step 1

Hi there! Since you have posted multiple subparts, we will answer the first three subparts for you.

 

The types of errors have to be identified in the above circumstances.

Random Errors: They are caused due to unknown and unpredictable changes in the experiment.

Systematic Errors: They usually occur with the measuring devices.

Human Errors: This is a mistake or a blunder done by the experimenter (eg. misreading an instrument)
