Question

Acidity is measured on the pH scale and can be modeled by pH = - logH⁺ where H is the acid concentration amount used to find the pH acidity level. A solution has a pH level of 6, the inverse function to find the acid concentration amount is represented as , H⁻¹(6)=10⁻⁶, where 10⁻⁶ is the acid concentration

amount..
Based on the original function, what does the 10⁻⁶ represent?
A 10⁻⁶M is the output value representing the acid concentration when given the acidity level.
B 10⁻⁶M is the input value representing the pH acidity level when given the acid concentration level.
C 10⁻⁶M is the input value for acid concentration when given the acidity level.
D 10⁻⁶M is the output value representing the pH acidity level when given the concentration level.

Answer 1

The 10^-6M represents the acid concentration of hydrogen ions when a solution has a pH level of 6, according to the equation pH = -log[H+]. It is the output value of the acid concentration given the pH level.

Step-by-step explanation:

The pH is a measure of the acidity or alkalinity of a solution, measured on a scale ranging from 0 to 14. The pH of a solution is calculated using the equation ph = -log[H+], where [H+] is the concentration of hydrogen ions in moles per liter (M). When a solution has a pH level of 6, it means the hydrogen ion concentration is 10-6M. Therefore, the correct interpretation of the 10-6 in this context is that it's the acid concentration amount of hydrogen ions in the solution.

Given the inverse function H-1(6)=10-6, the 10-6M represents the output value of the hydrogen-ion concentration when the pH level is used as the input. Hence, option A is correct: 10-6M is the output value representing the acid concentration when given the acidity level.
