Which instrument is necessary to execute a titration?Question 3Select one:a.balanceb.graduated cylinderc.beakerd.burette

Break Down the Problem

1. Identify the purpose of a titration in chemistry.
2. Determine what instruments are typically used in the titration process.

Relevant Concepts

• Titration is a technique used to determine the concentration of a solution by reacting it with a reagent of known concentration.
• Common instruments used in titration include a burette, pipette, flask, and occasionally a balance for measuring solids.

Analysis and Detail

1. Burette: This instrument is essential in titration as it allows for the precise delivery of the titrant, which is the solution of known concentration. The ability to dispense the titrant dropwise makes it possible to locate the endpoint of the titration accurately.
2. Graduated Cylinder: While this instrument is useful for measuring liquid volumes, it is not typically used in titrations for delivering titrants.
3. Beaker: Beakers can hold solutions but are not used for dispensing accurate volumes required in titrations.
4. Balance: A balance measures mass but is not specifically used for executing titrations.

Verify and Summarize

The key instrument required for titration is the burette, as it allows for controlled and precise addition of the titrant to the analyte.

Final Answer

The necessary instrument to execute a titration is d. burette.
