Size of concentration of hydrogen ions ionized by water in sodium hydroxide with pH of 2, PH of acetic acid, PH of hydrochloric acid, PH of 12, PH of ammonia, PH of 12

[H+]=10^-12mol/L in ammonia and NaOH with pH=12, all of which are separated by water
In HAc and HCl with pH=2,[ H+]=10^-2mol/L,[ OH-]=10^-12mol/L, these OH- are all ionized by water, and when water ionizes one H+, it must simultaneously ionize one H+, so the H+ ionized by water is also 10^-12mol/L
In all cases, the H+ of water ionization is 10^-12mol/L

If the degree of ionization of water in pure water is. alpha.1, the degree of ionization of water in hydrochloric acid at pH=x is. alpha.2, and the degree of ionization of water in ammonia at pH=y If the ionization degree of water in pure water is α1, the ionization degree of hydrochloric acid in pH=x is α2, the ionization degree of ammonia in pH=y is α3, and the ionization degree of water in the solution after the two solutions are mixed in equal volume is α4, if x+y=14(where x≤6, y≥8) The size relationship between α1 and α3 is (α1=α3) The size relationship between α1 and α4 is (α1

Is the title wrong? 1) Should be a2= a3 or a1> a3 2) A1> a4
1) The degree of ionization of water is reduced because the pH=y is basic to suppress the ionization of water
2) Since x+y=14, it can be known that c (H+) in hydrochloric acid is equal to c (OH-) in ammonia water before reaction, and the solution is alkaline after equal volume mixing, so the ionization degree of water is less than pure water a4
