View the step-by-step solution to:


1: How might the pH, and by extension the color, of the standard solutions be affected if the

dissolved carbon dioxide in the deionized water is not removed before beginning the experiment?

2: If the series of dilutions had started with 2.0M HCl instead of 1.0M HCl, would there be an effect on the colors of the indicators in each of the dilutions? If so list themjQuery224018762197991809748_1575185386440?

3: Determine the approximate concentration of your NaOH solution made in "Preparation of NaOH Standard."

This how -Preparation of NaOH Standard:

---Using a graduated cylinder, transfer about 100mL of 1M NaOHinto a large beaker (600mL or larger). With continuous stirring, dilute with deionized water until the total volume is approximately 500mL. Cover the solution with a large watch glass and label the beaker as NaOH solution.

4: Using your result in question #3, calculate the mass of oxalic acid dihydrate required to react with 15mL of your NaOH solution.
