3. Calculate the concentration of an aqueous solution of Ca(OH)2 that has a pH of 12.39 express answer using 2 sig figs
The concept used to solve this problem is to determine the concentration of aqueous solutions of base form given.
The of any substance is defined as the negative logarithm of the hydrogen ion concentration.
If the of any solution is 7 then the solution is neutral. If the is 0 to 7 then the solution is acidic and if the of the solution is 7 to 14 then the solution is basic.
It also defined the concentration of hydrogen ion of the solution:
The is determined the nature of solution, which is defined as:
It also defined the concentration of hydroxide ion of the solution:
Thus, the concentration of an aqueous solution of that has a pH of 12.09 is.
Part BThus, the concentration of an aqueous solution of that has a pH of 12.91 is.
Part CThus, the concentration of an aqueous solution of that has a pH of 12.39 is.
