(a) Interpretation: Whether the equivalence point of NaHCO 2 ( a q ) when titrated with NaOH ( a q ) will be below, above or at pH 7 needs to be determined. Concept introduction: Titration is the process where a known concentrated solution is used to identify the concentration of an unknown solution. Here the known solution which is called as titrant is added to the unknown solution which is called as analyte until the reaction is complete.

The sum of the numbers in the name of isA. 11; B. 13; C. 10; D. 12; E. none of the other answers iscorrect. I believe the awnser should be E to this problem but the solution to this problem is D 12. I'm honestly unsure how that's the solution. If you can please explain the steps to this type of problem and how to approach a problem like this it would be greatly appreciated!
