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
