Answer:
The [H⁺] of the solution is 1.74*10⁻⁹ M
Step-by-step explanation:
pH, short for Hydrogen Potential, is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance. The pH scale ranges from 0 to 14. Values less than 7 indicate the acidity range and those greater than 7 indicate alkalinity or basicity. Value 7 is considered neutral.
The pH is calculated as the negative logarithm (base 10) of the molar concentration of the hydrogen or proton ions (H⁺) or hydronium ions (H₃O⁺).
pH= - log [H⁺] = -log [H₃O⁺]
In this case, you know that pH= 8.76. Replacing in the definition of pH:
8.76 = -log [H⁺]
Solving:
[H⁺]= 10⁽⁻⁸ ⁷⁶⁾
[H⁺]= 1.74*10⁻⁹ M
The [H⁺] of the solution is 1.74*10⁻⁹ M
