Question 1

A burette is used to titrate 10.0 mL of nitric acid with a 0.15 M NaOH solution. According to the burette reading shown in the image, what is the volume of NaOH delivered to reach the equivalence point?

Accepted Answer

14.70 mL

Question 2

Given the burette reading in the image, if 14.70 mL of 0.15 M NaOH was required to neutralize 10.0 mL of HNO$$_3$$, what is the concentration of the nitric acid? Use the equation $$M_1V_1 = M_2V_2.$$

Accepted Answer

$$0.22\ \mathrm{M}$$

Question 3

If the burette reading started at 12.00 mL and ended at 14.70 mL, what is the total volume of titrant delivered?

Accepted Answer

2.70 mL

Question 4

During a titration, why is it important to read the burette at the bottom of the meniscus, as shown in the image?

Accepted Answer

To avoid parallax error and ensure accurate volume measurement
