Estimation of pH Essay

Acid-base titration calculationsAimThis essay is designed to train our skills of calculation in titration as well as help us to be familiar with the procedures of titration.Background1. Titration is a technique which involves measuring the spate of one solution which just reacts solely with another solution.2. A pipette is designed to deliver exactly the same volume each duration it is used.3. A burette is equipment fitted with a tap and is calibrated so as to accurately measure a variable volume of solution.4. Tire is the volume of the second solution required in titration.MethodThe full experiment is based on computer simulation. To train our calculation skills in titration, two discharges are set. virtuoso is titration between a strong blistering and a strong base. The other is between a indistinct acid and a strong base. In this experiment, the strong acid is HCl, the strong base is NaOH and the weak acid is CH3COOH.Strong acid and strong base1. roofy up the apparatus.2. Measure 25ml Ba(OH)2 by pipette.3.

As what I have discovered, all the graphs of a certain reaction in this software are the same. There is no difference in the graph if the concentration is changed. Also the graph is distinct points rather than a curve. During the experiment, sometimes failure occurred. Thus the only improvement could be make is to change another software.
