Re: A group of students in Chemistry 1412 are considering the following questio

None of these answers is really correct, a better answer would be: f]ANY of 
the above.  

The question asked [or the information given] is incomplete, or erroneous.

Is a strong [or a weak] acid reacting with a strong or a weak] base? What 
is the nature of the salt that is formed? Will it hydrolyse?

I assume that when the acid reacts with the base in "equal proportions", 
this means that one mole [or equivalent] of acid with one mole [or 
equivalent] of base, that one mole or formula weight, or equivalent weight 
of salt is formed, with no acid or base left over.

One mole  [or eq.wt.] of HCl reacts with one mole [or eq.wt.] of NaOH, to 
form one mole of NaCl.  The solution will be nearly neutral,i.e. pH =7.

1 mole NaOH and 1 mole of Acetic acid, Sodium acetate is formed. 
A 0.1 Molar solution of sodium acetate has a pH = 8.9

Ammonium Hydroxide and NaOH, same conditions. Ammonium Chloride is formed, 
and a 1 Molar solution of this a pH of about 5.

  Maybe one of the "Super Acids' would react with a very weak base yield a 
pH of O, but I cant think of a good example. Conversely,  for pH=14.

The equations for the pH of a salt are given in any chemistry text or the 
CRC or LANGE'S handbooks.
