VI. Questions 1. How would the resulting actual molarity be affected in the following scenarios? (increase, decrease change, or could increase or decrease). Explain each one. A. A few salt crystals remain behind on your weigh boat or funnel. B. An unconditioned pipet, recently washed with DI water & still wet inside, is used to pipet NaCl solution. C. You fill the volumetric flask slightly past the calibration mark. D. You do not reweigh your 50 mL Erlenmeyer flask after dumping the solution from the previous trial. 2. With regards to this experiment: A. Sketch a sample standard curve (with 3 data points) that has a poor (low) R2 value, but still provides an accurate density determination. B. Should you be confident when using equations with low R2 values? How could you improve the R2 value without redoing any previous data points. C. Will a high R² value always provide an accurate answer? Explain with a plotted example. only)
