Three 15.0 mL acid samples – 0.10 M HA, 0.10 M HB, and 0.10 M H2C – are all titrated with 0.100 M NaOH. If HA is a weak acid, HB is a strong acid, and H2C is a diprotic acid, which statement is true of all three titrations?

a. All three titrations have the same final pH.

b. All three titrations require the same volume of NaOH to reach the first equivalence point.

c. All three titrations have the same pH at the first equivalence point.

d. All three titrations have the same initial pH.

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
