Answer
Equipment A, which is a burette, is filled with the acid solution. To measure the volume of acid, the initial reading on the burette is noted. After adding the acid to neutralize the base, the final reading is taken. The volume of acid used can then be calculated by subtracting the initial reading from the final reading.
It's important to watch for a color change in the indicator used to signal the endpoint of the neutralization.
Step 3
Name a suitable acid and name a suitable base for the preparation of sodium chloride by this method.
