In a solution, when the concentrations of OH- and H+ are multiplied, we always get the product 10-14.
For Solution A -
Given, [OH-] = 3.05 x 10-7 M
![[OH-] X (H30+1; = 10-14](http://img.homeworklib.com/questions/2a9df3a0-bbbc-11ea-99a2-153637f01e04.png?x-oss-process=image/resize,w_560)

For solution C -
![10-14 OH] = 6.27X10-4](http://img.homeworklib.com/questions/2e0f0dc0-bbbc-11ea-9a37-758a53cd1bc8.png?x-oss-process=image/resize,w_560)
![[OH-] = 1.59X10-11 M](http://img.homeworklib.com/questions/2e6092b0-bbbc-11ea-9928-e1465cc63425.png?x-oss-process=image/resize,w_560)
A solution is said to be basic if [H3O+] < 10-7 and acidic if [H3O+] > 10-7
Similarly, a solution is basic if [OH-] > 10-7 and acidic if [OH-] < 10-7
So, Solution A is basic because [OH-] > 10-7
That is , 3.05 x 10-7 M > 10-7
Solution B is basic because [H3O+] < 10-7
That is, 7.77 X 10-9 < 10-7
Solution C is acidic because [H3O+] > 10-7
That is, 6.27 X 10-4 > 10-7
