Question

Which acid-base titration would yield a titration

science chemistry

Answer 1

Answer #1

this acid base contains:

weak acids, and 3 equivalence points

then

ignore a; since H2CO3 only as 2 points

b) will be a good answer, but pH is low, therefore the titrant is NaOH, not H3PO4

c)

salt + HCl wont form this

d)

strong acid + storng base, do not expect this

e)

this is a good answer, since acid is being titrated by NaOH, there will be three eqoivalenc epoints!
