What is the procedure of acid-base titration?

An acid-base titration is an experimental procedure used to determined the unknown concentration of an acid or base by precisely neutralizing it with an acid or base of known concentration. At the equivalence point, the total amount of acid (or base) is recorded from the burette readings.

How do you do titration problems step by step?

What is citric acid titration?

When titrated by a strong base such as 0.1 M NaOH solution, a solution of citric acid traverses a buffer region during which the pH of the solution climbs gradually then more steeply. A visual acid-base indicator chosen for the titration must change from its acid colour to its base colour in the range 7 to 9.

How does temperature affect titration?

Any property of the solution that can be monitored and will change at the equivalence point can be used for a titration. The temperature will increase as long as the reaction continues, then decreases as excess titrant is added.

What is a titration and how is it performed?

A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. Typically, the titrant (the know solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction is complete.

What happens during titration?

In a titration, a solution of known concentration (the titrant) is added to a solution of the substance being studied (the analyte). In an acid-base titration, the titrant is a strong base or a strong acid, and the analyte is an acid or a base, respectively.

What is the endpoint of a titration?

titration. indicator colour change is the end point of the titration. The end point is used as an approximation of the equivalence point and is employed, with the known concentration of the titrant, to calculate the amount or concentration of the analyte.

Does titration produce heat?

The simple answer is yes.

What factors affect titration?

The Titration Process Is Influenced by the Following Factors:

• Measuring method.
• Instrument (instrument uncertainty/abrasion of the burette)
• Electrodes (electrode uncertainty/alteration of electrodes)
• Handling.
• Balance (weighing error)
• Temperature.

How do you perform a titration?

Record the pH value in the data table as “pH initial.” Place the flask under the NaOH burette and add the base slowly, drop by drop while swirling the solution. Watch the solution carefully, when the last drop added causes the solution to change color the titration is close to completion.
