LABORATORY 8 Post-Lab 1. Explain how each of the following errors would have altered your results. Clearly explain why your calculated answer would be high, low, or unchanged. (A single word answer is not acceptable.) a. You decided to take the pH after each addition of 5.0 mL of NaOH rather than after every 0.5 mL during the neutralization of your acid sample. b. While using the Half Volume method, your solution was dark pink (you overshot the endpoint) and...
