Answer to Question #51828 in Physical Chemistry for Souvik
The pH of Ca(OH)2 solution is 12.Find the number of milliomoles of Ca(OH)2 present in its 100ml solution.
The concentration of Ca(OH)2 will be equal to concentration of OH- in the solution. pOH of the solution is 14-12 = 2. [OH-] = 10^-2 The number of moles of Ca(OH)2 present in its 100ml solution is: 10^-2*0.1 = 10^-3 moles = 1mole.
