Final answer:
To find the hydrogen ion concentration [H+] from a pOH of 10.27, subtract the pOH from 14 to get the pH, then use the formula [H+] = 10^-pH to find the concentration. The calculated concentration is 1.85 x 10^-4 M.
Step-by-step explanation:
The student asks about calculating the hydrogen ion concentration [H+] of an acidic solution when the pOH is given as 10.27. In chemistry, the relationship between pH, pOH, and hydrogen ion concentration can be used to determine the acidity or basicity of a solution. The pH and pOH of a solution are related by the equation pH + pOH = 14. Since the solution is acidic, we can expect the pH to be less than 7. To find the hydrogen ion concentration, we can use the formula [H+] = 10-pH, where pH = 14 - pOH.
Since the pOH is 10.27, the pH would be 14 - 10.27 = 3.73. Therefore, the hydrogen ion concentration of the solution is calculated as [H+] = 10-3.73. This means the hydrogen ion concentration is 1.85 x 10-4 M, rounded to two significant figures because of the given pOH value.
