Someone knows how to solve this? It was found that 0.0005 mol of Ca (OH) 2 dissolved in 100 cm3 of solution is 80% dissociated. Calculate the pH of this solution.

pH = 11.9

Explanation:

First, we determine the number of OH⁻ moles dissolved:

80% of Ca(OH)₂ is dissolved:

There are two OH⁻ moles per Ca(OH)₂ mol:

Now we can calculate the molar concentration of OH⁻ (moles/L):

Then we calculate the pOH of the solution:

Finally, we can calculate the pH of the solution using the equation

sure what is it? ^w^

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
