Which base is the strongest? [h+] = 1 x 10-9 [h+] = 1 x 10-11 [h+] = 1 x 10-10 [h+] = 1 x 10-12

The strong base  is with concentration equals to .

Explanation:

The pH of the solution is defined as negative logarithm of ions in a solution.Higher the ions concentration lower will be the value of pH and more acidic will be the solution.

1)

Most acidic solution

2)

3)

4)

Most basic solution
