Indicate how your calculated NaOH concentration would be in error (is it higher, lower, or unaffected by the following details of the titration. In each case, explain your reasoning. a) You over-shot the end-point b) While titrating you noticed drops of solution clinging on the inner walls of the buret above the solution level c) You added ~10 mLs of water to the KHP solution while titrating d) You noticed an air bubble trapped in stopcock which is no longer present at end of titration. e) In placing the KHP solution under buret you spilled a little KHP solution on the bench.
