Question
- In an experiment, you need a concentration unit that is not sensitive to temperature changes. Which concentration unit best meets this? Give me a piece of brief information about that concentration unit (e.g. formula, definition, etc.).
- Calculate the pH of the following solutions:
- 1.8×10-9 M Ba(OH)2
- 0.0221 M HNO3
- 0.0056 M NaHCO3
- 0.065 M NaCl
- 0.015 M NH4Cl
- Calculate the arithmetic mean, median, and standard deviation of the actual temperature values measured for your location (your city of origin) for April 2020. Check out if there are susceptible values within your data sets. If necessary, apply a Q-test.
