Answer:water self-ionize to form an equilibrium system that has [h30+]=1.0x10^-7 M
Explanation:
Water self-ionizes to form an equilibrium system that has [H3O+] = 1.0 × 10–7 M best explains why pure water has a pH of 7.
What is Water?
This is defined as a universal solvent which comprises of the chemical elements hydrogen and oxygen.
Pure water has a pH of 7 as a result of it being able to self-ionize to form an equilibrium system that has [H3O+] = 1.0 × 10–7 M which is why option C was chosen.
