The pH level of a substance can be determined by the formula pH = –log[H+], where [H+] is the hydrogen ion concentration in moles per liter. An alkaline substance has a pH level between 7 and 14. Which ion concentration corresponds to an alkaline substance? 3.5 x 10^-16
5.0 x 10^-12
1.0 x 10^-7
1.1 x 10^-4
Please answer asap

B. 5.0 × 10⁻¹² moles per liter.

Step-by-step explanation:

In this exercise we have to calculate the pH levels associated with respective hydrogen ion concentration based on the following formula:

Where is the hydrogen ion concentration, measured in moles per liter.

a) 3.5 × 10⁻¹⁶ moles per liter:

The substance is above the upper bound for alkaline substances.

b) 5.0 × 10⁻¹² moles per liter:

The substance is alkaline.

c) 1.0 × 10⁻⁷ moles per liter:

The substance is not acid nor alkaline.

d) 1.1 × 10⁻⁴ moles per liter:

The substance is acid.

Thus, we concluded that correct answer is B.
