DBE Chemistry 2023 November Exam

This is one of the most interesting papers I’ve done in a long time. There were some questions that require a bit of thinking but for the most part the paper was just fine. I hope you find my explanations helpful. Enjoy!!! #mlungisinkosi #matric #grade12 #chemistry #pastpapersolution

On 7.2.2) It is said we must calculate the pH of the solution after step 1 has occurred. The pH will be determined by the access HNO3, so we have to calculate the concentration of HNO3 before it is neutralized by Ba(OH)2
So the volume we'll use is 25cm³

I am not able to understand why the conc of 0, 13 went with 30cm³ instead of 50cm³ for Q5 no.5, 3. Can someone pls explain it to me

[SiyandaNgubane-sjsu]

Sir I'm not sure if i do understand 7.2.2. Ain't we suppose to calculate the amount of HNO3 that was unused
