Answer:
The weight of the displaced water is equal to the upthrust acting on the stone which is less than the weight of the stone thus the stone sinks to the bottom of the beaker. This is according to the Archimedes principle which states that when an object is partially or wholly immersed in a fluid the weight of the displaced fluid is equal to the upthrust acting on the object.
The volume of titrant required for the titration would be 19.81 mL.
Since the burette was not filled to the zero mark during the titration and the level of base titrant was not filled to the 2.42 mL mark. As a result, the difference between the two values represents the total amount of titrant used in the titration.
therefore,
Volume of titrant after running titration - Volume of titrant before running titration = total titrant required for the titration
22.23 - 2.42 = 19.81 mL
What Exactly Is Titration?
Titration is a laboratory technique that uses a solution with known volume and concentration to determine the concentration of an unknown solution. Between the two solutions, an oxidation-reduction reaction or acid-base neutralization occurs, and the known quantities are used to calculate the unknown. The known concentration standard solution is referred to as the titrant or titrator, while the unknown concentration solution is referred to as the titrand or analyte.

Whereas ionic bonds join metals to non-metals, metallic bonding joins a bulk of metal atoms. ... Sodium metal is therefore written as Na, not Na+. ... Both of these factors increase the strength of the bond still further. ... Heat capacity: This is explained by the ability of free electrons to move about the solid.
