Problem
A student adds 0.30 mL of titrant beyond the first persistent color change when titrating a monoprotic acid. How will this error most likely affect the calculated molarity of the acid, and what type of experimental error does it represent?
(a) The calculated molarity will be unaffected; the error is systematic.
(b) The calculated molarity will be too high; the error is systematic.
(c) The calculated molarity will be too low; the error is systematic.
(d) The calculated molarity will be too high; the error is random.
