There are 5 bottles in front of you, each with a label.Bottle A: "Neutral"Bottle B: "[H3O+] = 1 x 10-10 mol/L"Bottle C: "pOH = 5Bottle D: "pH = 3"Bottle E: "[OH-] = 1x 10-12 mol/L"Classify bottles according to the basicity of their contents, from the most basic to theless basic. Justify the ranking with a few sentences and/or a few calculations.

[tex]\begin{gathered} pOH(D)=14-pH \\ pOH(D)=14-3 \\ pOH(D)=11 \end{gathered}[/tex]

Bottle A neutral has a pH of 7

On the pH scale a pH greater than 7 is basic, 14 is the most most basic. The order of bottles arranged from most basic to least basic is:

Bottle E: 12

Bottle D: 11

Bottle A: 7

Bottle C: 5

Bottle B: 4
