The answer is 10-12. The relationship of pH and [H+] is pH = -lg[H+]. And the higher pH, the stronger base is. So the strongest base has the lowest concentration of H+.

Answer:The strongest base with [tex]H^+][/tex] concentration is [tex][H^+]=10^{-12} M[/tex].

Explanation:

[tex]pH=-\log[H^+][/tex]

Higher the pH value less will be the concentration of [tex][H^+][/tex] ion concentration and stronger will be the base.

1. [tex][H^+]=10^{-9} M[/tex]

[tex]pH=-\log[10^{-9}]=9[/tex]

2.[tex][H^+]=10^{-11} M[/tex]

[tex]pH=-\log[10^{-11}]=11[/tex]

3.[tex][H^+]=10^{-10} M[/tex]

[tex]pH=-\log[10^{-10}]=10[/tex]

4.[tex][H^+]=10^{-12} M[/tex]

[tex]pH=-\log[10^{-12}]=12[/tex]

The strongest base with [tex]H^+[/tex]concentration is [tex][H^+]=10^{-12} M[/tex].
