The usual range of pH values encountered is between 0 and
14, with 0 being the value for concentrated hydrochloric
acid (1 M HCl), 7 the value for pure water (neutral pH),
and 14 being the value for concentrated sodium hydroxide (1
M NaOH). It is possible to get a pH of -1 with 10 M HCl,
but that is about a practical limit of acidity. At the
other extreme, a 10 M solution of NaOH would have a pH of
15.
