Answer:
pH can be different from 7 ( second statement is false)
Step-by-step explanation:
since
pH=pKa + log [A-]/[HA]
at half of the equivalence point
[HA]= [A-] (third statement is true)
and therefore
pH = pKa (first statement is true)
since pH = pKa , pH can be different from 7 ( second statement is false)
Answer:
If the discount is 32%, the new price would be $26.486
