4. A solution of the weak base, ammonia (NH3), was completely neutralized with the strong acid HCl. Write out the dominant equilibrium (including phase labels) that would exist in this "neutralized" solution. HINT: first look at what ions would exist in solution after the non-equilibrium reaction with the strong acid is over. Second, decide if either of these ions is an acid or a base. Lastly, write the equation for this ion acting as an acid or base in water.

Predominant equilibrium:

Explanation:

Neutralization reaction:

In neutralized solution, and ions exist.

We know that is an weak base and HCl is a strong acid.

So, is a strong conjugate acid of  and is an weak conjugate base of HCl.

Hence, in neutralized solution, will be predominantly hydrolyzed into and .

So, predominant equilibrium:

i have no clue hope you find the answer

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
