Question
a) BURET BEFORE TITRATION: Above is a buret with NaOH solution before the titration begins. Read the volume to the nearest hundredth of a mL. Tolerance is set absolute to +/- 0.02 mL. READING/ENDPOINT IS 1.45
b) BURET AFTER TITRATION: Above is a buret with NaOH solution after the end point of the titration. Read the volume to the nearest hundredth of a mL. Tolerance is set absolute to +/- 0.02 mL. READING/ENDPOINT IS 16.72
LEFT IS A RIGHT IS B
please answer
a) BURET BEFORE TITRATION: Above is a buret with NaOH solution before the titration begins. Read the volume to the nearest hundredth of a mL. Tolerance is set absolute to +/- 0.02 mL. READING/ENDPOINT IS 1.45 b) BURET AFTER TITRATION: Above is a buret with NaOH solution after the end point of the titration. Read the volume to the nearest hundredth of a mL. Tolerance is set absolute to +/- 0.02 mL. READING/ENDPOINT IS 16.72 LEFT IS A RIGHT IS B please answerExplanation / Answer
a). Tolerance = +/- 0.02 mL
As provided in thhe question, the reading is 1.45 mL
for the calculation of absolute uncertainty in reading, the tolerance is taken into account.
so, the reading will become = 1.45 - 0.02
= 1.43 mL
b).
Tolerance = +/- 0.02 mL
As provided in thhe question, the reading is 16.72 mL
for the calculation of absolute uncertainty in reading, the tolerance is taken into account.
so, the reading will become = 16.72 - 0.02
= 16.70 mL
