Acid/Base Questions: True or False?

[parwana]

Answer the following questions t or f



a) Combining 0.3 moles of any acid with 0.3 moles of any base in water will always result in a pH value of 7.0

b) A 1 M solution of HCl and a 1 M solution of HNO3 have identical pOH values

c) Combining equal volumes of a 0.3 M acetic acid solution and a 0.3 M NaOH solution results in a buffer

d) The pH of a 1.0 M HCl (a strong acid) solution is 1.0

e) A 1 M solution of acetic acid (pKa = 4.75) and a 1 M solution of HCN (pKa = 9.20) have identical pH values



I would think abc would be false, d would be true, and e would be false. Please help

If you could tell why you think each answer is right or wrong, it would be easier to help.

In reality all are false, but one answer may depend on your education level.
