The hydronium ion concentration when pH = 7 is : 8.75 * 10⁻⁹ mole/liter
<h3>Determine hydronium ion concentration when pH = 7 </h3>
Given that :
pH = 8.0
Hydronium ion concentration = 1 * 10⁻⁸ mole/liter
Resolving the question
8.0 = 1 * 10⁻⁸ mole/liter
7.0 = x
therefore :
x = 7 ( 1 * 10⁻⁸ ) / 8.0
= 8.75 * 10⁻⁹ mole/liter
Hence we can conclude that The hydronium ion concentration when pH = 7 is : 8.75 * 10⁻⁹ mole/liter

Ionic compounds are formed by a positive ion called cation and a negative ion called anion.
I will show you some examples:
NaCl is formed by the cation Na+ and the anion Cl -
CaF2 is formed by the cation Ca 2+ and the anion F -
Li2O if formd by the cation Li + and the anion O 2-.
To tell that you use the oxidation number of each element. I did it this way
Ca F2 => Ca has oxidation number 2+ and F has oxidation number 1- then the ions have that very same charge number.
