For each of the following errors, tell whether your calculated molecular weight would be too high, too low, or unaffected. a) unawares, you inadvertently spilled some solute(so it didn't make it into the test tube) after it was weighed out. b) your thermometer is poorly calibrated and reads 0.3C lower than the actual temperature. c) while mixing the solution you spilled some over the sides of the test tube. Assume the solution was well mixed before the spill occurred.

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...

1. For each of the following situations, determine whether the calculated Molarity of the acetic acid would be too high or too low compared to the actual value. a. Some of the drops of vinegar stuck to the sides of the well plate instead of going to the bottom of the well b. You added NaOH until the solution was a very dark pink C. You miscounted and instead of adding 20 drops of vinegar, you only added 18
