Question

The concentration of hydronium ions is greater than 1 x 10^−7 for acidic solutions. True False

Answer 1

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:

$pH=-log\lbrack H_3O^+].$

Now, let's replace the value of the given concentration in the formula, which is 1 x 10⁻⁷:

$pH=-log\lbrack1\cdot10^{-7}]=7.$

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.
