Homework Answers
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.
![pH = -log[1,01]](http://img.homeworklib.com/questions/e8ea7460-240d-11eb-b45e-458a2e644c61.png?x-oss-process=image/resize,w_560)
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:
![[4,0*] =10-P](http://img.homeworklib.com/questions/e94659c0-240d-11eb-82b7-3de6c448c5ad.png?x-oss-process=image/resize,w_560)
The 
is determined the nature of solution, which is defined as:
![POH = -log. [OH]](http://img.homeworklib.com/questions/e9a32150-240d-11eb-bff3-0d4b92f29c64.png?x-oss-process=image/resize,w_560)
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
.
Thus, the concentration of an aqueous solution of 
that has a pH of 12.91 is
.
Thus, the concentration of an aqueous solution of that has a pH of 12.39 is
.
