Answer:
True.
Explanation:
Remember that hydronium ions indicate the concentration of an acid.
On the pH scale, the acids are between 0 and 7, and for bases, the pH is between 7 and 14.
The formula to calculate the pH of an acid is the following:
[tex]pH=-log\lbrack H_3O^+].[/tex]Now, let's replace the value of the given concentration in the formula, which is 1 x 10⁻⁷:
[tex]pH=-log\lbrack1\cdot10^{-7}]=7.[/tex]You can note that if the value of hydronium concentration is greater than 1 x 10⁻⁷, and we replace it in the formula, we will obtain lower pHs, which means that it is an acidic solution.
The answer would be true.
