Mixtures
Explanation:
The forms of matter that exists without having chemical bonds between them are mixtures.
Mixtures are impure substances. They are made of matter that are not chemically bonded to one another.
Here are some of the characteristics of a mixture:
- Composition is indefinite i.e they consist of two or more elements and or compounds in any proportion by mass
- The constituents retain their identities i.e physical properties are not altered.
- The constituents reacts differently to changed conditions.
- They can easily be separated into constituents by physical methods.
Many natural mixtures exists and several others can be formulated. Examples include air, sea-water, muddy water, alloys e.t.c

Answer:
At a greater value of pH, [H⁺] is really low.
Solution with pH = 8 has more [H⁺] than solution at pH =12.
Explanation:
pH = - log [H⁺]
10^-pH = [H⁺]
At pH = 8, [H⁺] = 10⁻⁸ → 1×10⁻⁸ M
At pH = 12, [H⁺] = 10⁻¹² → 1×10⁻¹² M
In conclussion, at a greater value of pH, [H⁺] will be really low.
Solution with pH = 8 has more [H⁺] than solution at pH =12.
