Lab Report Titration

Lab report titration

The aim is to demonstrate the rapid change in PH that occurs during neutralisation using thegradient of a graph. Moreover, we will try to lab report titration the typical increase in PH at thebeginning of the weak acid titration. The experiment was carried out using a burette, an electronic PH-meter, a magnet stirrer and abeaker.

It illustrates several typical features of a lab report titration acid strong basetitration. Strong Acid titration 0. These are:- The possibility of contamination https://modernalternativemama.com/wp-content/custom/personal-statement/themes-robert-frosts-poetry.php the solution through the equipment such asbeakers, burettes etc. Indeed, although wecalibrate the device using a known buffer solution, we do not precisely know theaccuracy and reliability of this calibration.

Such limitations are uncontrolled and will induce systematic errors that would harm allreadings in a similar manner. As a result, they do not directly affect the evaluation of thegraphs.

Evaluation and conclusion The aim of the experiment was to reflect on the various characteristics of strong and weakacid titrations. We have used accurate equipment to measure the pH and volume thus errorsare within an acceptable range. The experiments did not involve any other chemical orsubjective human decision such as colour change from an indicator. As a result, we may arguethat the experiment was a success as we have lab report titration able to achieve the aims within acceptable - It is only at the neutralisation point that the pH abruptly increases reaching basicvalues.

This is a graphical estimation thus we cannot apply the same errors as lab report titration normalresults. To find this result, we have found the average between 32 and The error therefore contains both values. The graph also illustrates several typical features ofCharacteristic initial riseNeutralisation weak acid titrations.

These are:- The initial pH is 3 meaning it is a concentrated solution of a weak acid. We couldargue that a similar pH would be obtained with a diluted strong acid, however, othertypical features disprove the arguments. Thisis a special characteristic of weak acid neutralisation. Also, the range of pH over which neutralisation takes placeis smaller and less clear. The graph does not change gradient lab report titration abruptly as in graph 1- Click the following article graph eventually tends asymptotically towards pH 12 meaning the base is onceagain 0.

This takes place because the strongbase neutralises some of the acid molecules forming its conjugate base of the weakacid. As a result, it is a buffersolution.

This is typical of weak acid titrations. Experimental limitations and improvements The errors on measurements throughout the entire experiment come from the inherentlimitation of the apparatus used. These are:- 0.]
