r Analysis Questions for Acid-Base Titration Experiment In standardizing the solution of aqueous sodium hydroxide, a chemist overshoots the end point and adds too much NaOH(aq). Would this error result in a calculated concentration of NaOH that was overestimated or underestimated? Explain your reasoning 2. In the titration of the unknown diprotic acid, assume a chemist uses a standardized solution of NaOH that has been underestimated in its concentration. How would this error affect the final calculation for the molar mass of the unknown acid? Would it be over remain unaffected? Explain your reasoning. estimated, underestimated or and adds too much NaOH. How would this error affect the final calculation for the molar mass of the unknown acid? Would it be overestimated, underestimated or remain unaffected? Explain your reasoning 3. In the titration of the unknown diprotic acid with NaOH, assume a chemist overshoots the end point

Explanation / Answer

1)

Here he will get error in the estimation of quatity of acid. Because we can conside the volume of NaOH for calculation of acid concentration. If we take wrong volume definitely we will get wrong values of concentration.

If we take extra volume, according to the following formula the quantity would be lesser compared with real value. Hence its underestimated value.
