WebbThe pH of a solution is 8.22. What are pOH, [H + ], and [OH − ]? Solution Because the sum of pH and pOH equals 14, we have 8.22 + pOH = 14 Subtracting 8.22 from 14, we get pOH = 5.78 Now we evaluate the following two expressions: [H+] = 10−8.22 [OH−] = 10−5.78 So [H+] = 6.0 × 10−9 M [OH−] = 1.7 × 10−6 M Test Yourself The pOH of a solution is 12.04. Webb27 mars 2024 · The lower the pH level, the stronger the fluid’s acidic levels. For example, battery acid has a pH of 0, which means it’s a very strong acid. The least acidic fluids are …
The pH scale ranges from 0 to 14, with a pH of 7 indicating neutrality, values less than 7 indicating acidity, and values greater than 7 indicating basicity. The pH scale is based on the hydrogen ion concentration, with each pH value representing a tenfold difference in hydrogen ion concentration. p [H] [ edit] Visa mer In chemistry, pH , also referred to as acidity, historically denoting "potential of hydrogen" (or "power of hydrogen"), is a scale used to specify the acidity or basicity of an aqueous solution.
