how will know the hydroxide concentration for a solution with a pH of 10 at 25 degree celsius?
To determine the hydroxide ion (OH-) concentration for a solution with a pH of 10 at 25 degrees Celsius, you need to use the equation relating pH and pOH. The concentration of OH- can be calculated by obtaining the pOH value and then converting it back into concentration.
Here's the step-by-step approach:
Step 1: Calculate the pOH.
The pOH is obtained by subtracting the pH from 14 (pH + pOH = 14). In this case, since the pH is 10, the pOH would be: pOH = 14 - pH = 14 - 10 = 4.
Step 2: Convert pOH to [OH-] concentration.
The pOH value is a logarithmic representation of the hydroxide ion concentration. To convert it back to the concentration value, use the equation: [OH-] = 10^(-pOH).
In this case, [OH-] = 10^(-4), which equals 0.0001 M (or mol/L). So the hydroxide concentration for a solution with a pH of 10 at 25 degrees Celsius is 0.0001 M.
