why PH range 0-14 explain

Answer Posted / sasi

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.

2. Two grams of Benzoic acid are dissolved in 200 ml of water and extracted with 200 ml of diethyl ether. The distribution coefficient of benzoic acid is 100, and its dissociation constant is 6.5 10-5. Calculate the distribution ratio (D) of benzoic acid at pH 2, 5, and 6. 3. Calculate D at pH 2 to 10 (1 unit apart) in the above problem, and plot D versus pH.
