If a 0.143 g sample of a weak acid requires 25.30 ml of 0.1036 M NaOh to reach an equivalence point, what is the molar mass of the acid? (g/mol) Which of the following is true at the equivalence point of a titration of a weak acid (HA) with a strong base? Select one: a. The acid and base are all consumed and the resulting solution is acidic (pH<7) b. The acid and base are all consumed and the resulting solution is neutral (pH=7) c. The weak acid (HA) is converted to A- so the solution is acidic d. The acid and base are all consumed and the resulting solution doesn't have a pH e. The acid and base are all consumed and the resulting solution is basic (pH>7)

If a 0.143 g sample of a weak acid requires 25.30 ml of 0.1036 M NaOh to reach
an equivalence point, what is the molar mass of the acid? (g/mol)
Which of the following is true at the equivalence point of a titration of a weak acid
(HA) with a strong base?
Select one:
a. The acid and base are all consumed and the resulting solution is acidic (pH<7)
b. The acid and base are all consumed and the resulting solution is neutral (pH=7)
c. The weak acid (HA) is converted to A- so the solution is acidic
d. The acid and base are all consumed and the resulting solution doesn't have a
pH
e. The acid and base are all consumed and the resulting solution is basic (pH>7)
