what is the concentration of the hydroxide ion in an acidic solution?
If the soln is acidic, then pH <7; therefore, the pOH must be >7 and OH^- must be less than 1E-7
In an acidic solution, the concentration of hydroxide ions (OH-) is very low. The pH of an acidic solution is less than 7, indicating a high concentration of hydrogen ions (H+). In other words, the concentration of hydroxide ions is inversely proportional to the concentration of hydrogen ions.
In an acidic solution, the concentration of hydroxide ions (OH-) is very low. This is because acidic solutions have a high concentration of hydrogen ions (H+) and a low concentration of hydroxide ions.
To calculate the concentration of hydroxide ions in an acidic solution, you need to know the concentration of hydrogen ions. This can be determined using the pH scale. The pH of a solution is a measure of its acidity or basicity. A solution with a pH less than 7 is considered acidic, with a higher concentration of hydrogen ions than hydroxide ions.
To find the concentration of hydroxide ions (OH-) in an acidic solution, you can use the equation Kw = [H+][OH-], where Kw is the equilibrium constant for water and has a value of 1.0 x 10^-14 at 25 degrees Celsius.
Since we know that in an acidic solution the concentration of hydroxide ions is very low, we can assume that [OH-] is negligible compared to [H+]. Therefore, we can simplify the equation to Kw = [H+][OH-] ≈ [H+][0]. This means that the concentration of hydroxide ions in an acidic solution is approximately zero.
In summary, the concentration of hydroxide ions in an acidic solution is extremely low, almost negligible. It is overshadowed by the much higher concentration of hydrogen ions. The low concentration of hydroxide ions is what distinguishes an acidic solution from a basic one.
