[LHM]

An aqueous solution of ammonia has pH=x, and a solution of hydrochloric acid has pH=y; it is also known that x+y=14, and x>11. If equal volumes of these two solutions are mixed together, what would be the concentration of the various ions in the resulting solution in descending order?

A) [NH₄⁺]>[Cl^-]>[OH^-]>[H⁺]
B) [Cl^-]>[NH₄⁺]>[H⁺]>[OH^-]
C) [NH₄⁺]>[Cl^-]>[H⁺]>[OH^-]
D) [Cl^-]>[NH₄⁺]>[OH^-]>[H⁺]
E) [Cl^-]=[NH₄⁺]=[OH^-]=[H⁺]

[Hybrid]

suppose that x=13 so pH=13 and H= 10^-13 and hence OH=10^-1
and y=1 and then H=10^-1
NH4+ = OH- monobasic amine
and Cl- = H+ monoprotic acid . so all species are equal and actually the solution pH will be neutral .

Good start x=11
