Just wanted some input and guidance on my answers if they were correct or not. The questions are as follows:
(b)Two 0.0400 M acid solutions were prepared (labelled A1 and A2). One of them was a weak acid and the other was a strong acid. The pH of A1 was 4.52 and of A2 was 1.40. Assume that all activity coefficients are equal to 1.
(c) 25.00 ml of each of the acids in part (b) was titrated with 0.1000 M KOH.
(i) Sketch the pH titration curve expected for A1.
(ii) Sketch the graph expected for a conductimetric titration of A1.
(iii) On all sketches carefully label the axes and mark the end points.)
So I know that A1 is a weak acid and KOH is a strong base, my attempt for the pH titration curve and the conductimetric titration for A1 have been attached below.
Are my attempts correct? Have I done the following correct:
1. Have I used the correct titles for the axis for both graphs?
2. The ph of A1 is 4.52, I placed this on the starting point of the line for the graph of pH titration, is that correct?
3. 25 ml of KOH was used, is it correct then to end the x axis with 25 at the end like I have done?
4. Are the end points indicated for both graphs done correctly?
5. Is there anything I can add to my graphs to make them clearer?
The reason I am asking all these questions is because I am going off the notes provided by my teacher which don’t appear clear to me as I have never done the topic before so I just used the sample graphs presented without no titles or the like and had an attempt. Hence the reason for asking about some questions which seem very obvious like the one's referring to the title of the axis.
Any input would be greatly appreciated, thank you.
