Question
Chapter 19, Problem 19.140P
Interpretation Introduction
Interpretation:
pH of the unpolluted water has to be calculated at 25οC.
Concept Introduction:
pH:
pH is a scale used to specify the acidity or basicity a solution. It ranges from 0−14. pH 7.0 is considered as neutral solution, pH more than 7.0 is taken as basic solution whereas pH less than 7.0 is considered as acidic solution (at 25οC). It is the measurement of activity of free H+ and OH- in solution.
pKa:
pKa is the negative log of acid dissociation constant that determines the strength of the acid. Lower the pKa value stronger is the acid.
pKa1 is the 1st dissociation constant for the acid and pKa2 is the 2nd dissociation constant of the acid.
Solubility:
Solubility is defined as the maximum amount of the solute that can be dissolved in the solvent at equilibrium.
