A titration is a laboratory technique that is used to determine the concentration of a substance, typically an acid or a base, in a solution. It involves the use of a buret, which is a long, thin tube with a valve at one end and a measuring scale at the other. A known volume of the substance of interest is placed in the buret, and a solution of known concentration, called the titrant, is added to the substance. The titrant is typically a base if the substance of interest is an acid, or an acid if the substance of interest is a base.

The process of titration involves adding the titrant to the substance of interest in small increments, called aliquots, until the point of chemical equivalence is reached. This point is known as the endpoint of the titration, and it is marked by a change in the color of an indicator solution that is added to the substance of interest. The endpoint indicates that the acid and base have neutralized each other, forming a neutral solution.

In a titration lab report, the discussion section is used to interpret and analyze the results of the experiment. It is important to ensure that the results are accurate and reliable, and to identify any sources of error that may have occurred during the experiment.

One common source of error in titration experiments is the use of impure reagents. It is important to ensure that the reagents used in the experiment are pure, as impurities can affect the accuracy of the results. Another potential source of error is the use of incorrect equipment, such as a buret that is not properly calibrated. It is also important to ensure that the endpoint of the titration is accurately determined, as this can affect the accuracy of the results.

In the discussion section of a titration lab report, it is also important to compare the results of the experiment to theoretical values. This allows the researcher to determine whether the results of the experiment are consistent with the expected results. If the results differ significantly from the theoretical values, it may be necessary to identify the source of the error and to repeat the experiment.

Overall, the discussion section of a titration lab report is an important part of the experimental process, as it allows the researcher to interpret and analyze the results of the experiment, identify sources of error, and compare the results to theoretical values. By carefully considering and discussing the results of a titration experiment, researchers can ensure that the results are accurate and reliable, and can use this information to make informed decisions and draw conclusions.

The mole ratio and volume relates the concentration of the solutions. For H2SO4: 2 mole of NaOH reacted with 1 mole of H2SO4. The substance that becomes oxidised is known as the reducing agent. It was hypothesized that the potassium permanganate neutralized sodium oxalate completely and molarity of potassium permanganate could be determined by titration. A titration is a lab technique used to determine the volume of a solution that is needed to react with a given amount of another substance. If concentration of titrant is not exact, final result is not exact.

Another error could come from failure to stop the drip of KMn04 early enough which would produce an inaccurate volume of KMn04 used in the reaction based on the buret reading. To accomplish this the experiment was split into two parts; part A and Part B. Conclusion After performing this experiment it is apparent that the qualitative analysis of substances can be found using the titration technique preformed in lab. Besides, a piece of white tile that placed below the conical flask is used to enable us to detect the end point clearly, which the colourless solution changes to a light pink solution. A suitable indicator should be chosen, preferably one that will experience a change in color an end point close to the equivalence point of the reaction. And then, doing titration by standardized titrant is going to be second. At this stage we want a rough estimate of the amount of this solution it took to neutralize the unknown solution.

However, in the event the standard is a solid the molecular weight in this case would be four or five significant figures. Redox titration includes oxidation half reactions and reduction half reactions. Thus, a careful selection of the indicator will reduce the indicator error. The more the number of moles of the base is used the more number of moles are needed to neutralize. Experimental: For this experiment, burette, beaker, graduated cylinder, stirrer, dropper, funnel, sodium oxalate and potassium permanganate were used.

The initial and final readings on the burette prior to starting the titration and at the end point, respectively should be recorded. It is a good idea to carry out titrations in triplicate because we get a more precise value. The acid-base indicator indicates the endpoint of the titration by changing colour. Be sure to reset the lab for each trial. In this activity, your goal is to determine the molar concentration and strength of two acid solutions by conducting titrations with a base solution of known concentration.

The burette was neutralized by the acidic solution of sodium oxalate and then was cleaned with water. Finally, they suggest that further research is needed to explore the effects of caffeine on heart rate in different populations e. Titration is a method of chemical analysis. In addition, you should also discuss any limitations of your experiment and what further research needs to be done to answer the question that you were investigating. What is the purpose of the acid-base titration lab? This study had several limitations that should be acknowledged. The answer is closer to the exact value.

Secondly, they suggest that caffeine may not be an effective means of increasing heart rate in healthy adults, which could have implications for its use in sports medicine. We determined the molar mass of the Potassium hydrogen phthalate, for the unknown acids we calculated the molar mass and the Ka values. When an acid reacts with a base , they neutralize the individual acid and base properties and produce salt and water. Single drops of the titrant can sometimes make a permanent or temporary change in the indicator2. Redox reactions are a combination of two reactionsÍž oxidation and reduction reactions. The known solution should then be allowed out of the burette, into the conical flask.

By adding distilled water we would dilute the base in the Erlenmeyer and less volume of the acid would be required to neutralize the base. Interpreting the findings After you have introduced the findings of your experiment, you should then go on to interpret them. And as a result a salt NaCl and water were formed. You should also consider the implications of your findings and what they could mean for future research. After completion of the experiment, the burette was rinsed with water and solution was disposed to the waste.

For example, if you found that a drug did not affect heart rate, you would not say that it means that the drug is safe because further research would need to be done to confirm this. It also increases the accuracy of the answer. . The burette and pipette have some limitations due to being less precise. A Standardization of NaOH Purpose Upon completing this experiment the goal is to acquire the knowledge of the titration technique and its corresponding calculations. The buret contains a large air bubble in the tip, which disappears in the course of the titration.
