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

Explanation / 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
