# What is the volume reading for the liquid in the buret shown to the left? | |||
# The titrant calibration could use wet glassware, but the amino acid titration was supposed to use dry glassware. Why? | |||
# What common error did I do when I initially chose methyl red as the indicator? The table below may be helpful. | |||
# Using phenolphthalein, at what pH will the standardization titration solution color change to a light pink color? | |||
# Bonus: Assuming 0.500 g KHPhth, 20.00 mL water & 17.63 mL NaOH to neutralize solution, what is the pH at the equivalence point? | |||
