4. 20.0 mL of 0.100 M nitric acid is titrated with 0.0500 M barium hydroxide at 10°C. Write the net ionic equation for the titration reaction and calculate the pH at the equivalence point. Kw = 2.5 * 10-15 at
10°C.

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
