Which of the following is TRUE? Which of the following is TRUE? The equivalence point is where the amount of acid equals the amount of base during any acid-base titration. An indicator is not pH sensitive. At the equivalence point, the pH is always 7. A titration curve is a plot of pH vs. the [base]/[acid] ratio. None of the above are true.

Which of the following is NOT true regarding the value for pKa based on a titration curve using a pH electrode to determine the equivalence point? A.pKa = pH at 1/2 the volume of the equivalence point B.pKa for polyprotic acid = pH at 1/2 the volume of the equivalence point and represents the average response of all the acidic protons (i.e. different pKa values) C. pKa = pH at the equivalence point D. pKa = pH at the first...

An indicator is udeful in determining the equivalence point of a reaction if 1) the color change occurs on the vertical portion of the titration curve, and 2) the color change is sharp i.e, occurs over a small volume of added titrant (NaOH). On the basis of the pH/color changes observed, would you be able to carry out an acetic acid-NaOH titration by using an bromocresol green indicator and why? Would phenolphthaleinm colorless at pH 7.8 and pink at pH...

A portion of a titration curve is called the "buffer region". Which of the following best describes the buffer region? Assume the acids and bases are both MONOPROTIC. Select one: a. In the titration of a weak acid with a strong base, it is point before any base has been added. b. In the titration of a weak acid with a strong base, it is the region of the titration curve after some base has been added, but before the...

Equivalence Point is the point when the amount of Base added to the solution equals the amount of Acid. However, in another explanations, equivalence point is defined as when all the original acid is neutralized by the NaOH and compeleted converted into its conjugate base. The two explanation seems to be at odds with each other. The 2nd explanation states that there are no longer any original acid left, hence the acid: base ratio cannot the 1:1.

Which of the following statements about acid-base titrations are true? (i) If 0.200MNaOH is used to titrate 50.0mL of 0.100M hydrochloric acid, it will take 25.0mL of NaOH to reach the equivalence point. (ii) If 0.100MNaOH is used to titrate 50.0mL of 0.100M sulfuric acid (instead of 50.0mL of 0.100M hydrochloric acid), the pH at the equivalence point will be <7.00 because sulfuric acid is diprotic. (iii) The pH=7.00 at the equivalence point for a strong acid – strong base...
