Question

select all false statements.
(check all that apply)
the buret clamp is used to hold the buret.
the volume dispensed from a buret is calculated by subtracting the final volume from the initial volume.
a buret should be read to 2 decimal places.
the unknown solution goes into the buret.

Explanation:

• Statement 1: A buret clamp is indeed used to hold the buret. This is a correct statement.
• Statement 2: The volume dispensed from a buret is calculated as \(V = V_{final}-V_{initial}\), not \(V = V_{initial}-V_{final}\). So this statement is false.
• Statement 3: A buret is read to two decimal places (e.g., \(25.00\space mL\)). This is a correct statement.
• Statement 4: In a titration, the buret usually contains the titrant (a known - concentration solution), and the unknown solution is in the flask. So this statement is false.

Answer:

• B. The volume dispensed from a buret is calculated by subtracting the final volume from the initial volume.
• D. The unknown solution goes into the buret.
