If you were to overshoot tje endpoint in the titration of your unknown acid, would youncalculated molar mass be higher, lower or equal to the actual molar mass
For a weak acid/strong base titration, if the titration mixture is a dark pink, which of the following is correct? 1. The calculated concentration of weak acid is underestimated because the amount of strong base required to reach and endpoint is underestimated. 2. The calculated concentration of weak acid is overestimated because the amount of strong base required to reach the endpoint is overestimated 3. the calculated concentration of weak acid is underestimated because the amount of strong base required to reach the endpoint is overestimated
Why are the standard reagents used in neutralization titrations generally strong acids and bases ratherthan weak acids and bases? Explain.
5) A student starts a titration without phenolphthalein in the Erlenmeyer flask. The student realizes the mistake and adds the phenolphthalein during the titration. Once the phenolphthalein is added, the solution in the Erlenmeyer flask remains colorlessCan the results of this titration be used? Concisely explain .
2. Below is a titration curve generated by a similar titration to the ones simulated, Vinegar Titration Curve 14.00 13.00 12.00 11.00 10.00 9.00 8.00 * 7.00 6.00 5.00 4.00 3.00 2.00 1.00 0.00 0.00 5.00 10.00 15.00 20.00 25.00 30.00 35.00 Volume NaOH (mL) We can use this curve to estimate the pka of our weak acid by what is called the "half equivalence point method". The equivalence point is the middle of the steepest part of this graph. Estimate the volume of NaOH added to the titration at that point by using a rule or other straight edge to follow that point down to the x-axis. Divide that volume by 2 (half the equivalence point) and estimate the pH at that volume of NaOH using your straight edge again. pKa = pH at the half equivalence point. What do you estimate the pka to be? 3. The pka of acetic acid is 4.76. Calculate percent error between the true value and your estimated value from question 2.
