How would the following error affect this lab? When completing the titration a dark pink endpoint was obtained. O The dark pink endpoint means the endpoint was overshot. Since more NaOH was used, the neutralizing capacity of the antacid will be calculated as higher. The endpoint should be pink. There is no affect on calculations here. O The dark pink color indicates the endpoint is overshot. Since more NaOH was used, it will look li the mol of acid were higher. This will result in a weaker antacid (neutralizing capacity) being calculated. As long as both endpoints are the same color, no error will be calculated.

Can you please help me find these 3 final volume of buret (ml) , volume of naOH (ml) and molar out of acetic acid (M)
Compare conductivity titration to the pH-metric titration that you performed earlier. Do both methods yield the same equivalence point? Explain.
How do you find the molar mass of an unknown reagent in a titration setup given the reagent's density, volume, molarity and volume/volume percent?
If you have determined your pKa values and located the equivalence points on the graph, and then you use a stronger concentration of base to titrate the unknown acids, could you successfully locate the equivalence points and pKa values? If so, how and how you would have to adjust volumen(if needed) to have a successful titration
