The leaf compost jar and the control jar both contained the same initial volume and concentration of NaOH. Explain why the control jar required a larger volume of HCl than the leaf compost jar did to reach the end point of the titration.
A pair of students forgets to precipitate the carbonate ions in their leaf compost jar's NaOH solution prior to the HCl titration. How would this affect the perceived amount of NaOH present in the titrand?
How would forgetting to precipitate the carbonate ions affect the perceived amount of CO2 given off by the leaves?
