Hello!
In this case, since the pH of the given metal is 10.15, we can compute the pOH as shown below:
Now, we compute the concentration of hydroxyl ions in solution:
Now, since this hydroxide has the form MOH, we infer the concentration of OH- equals the concentration of M^+ at equilibrium, assuming the following ionization reaction:
Whose equilibrium expression is:
Therefore, the Ksp for the saturated solution turns out:
Best regards!
Answer : The pH will be, 3.2
Explanation :
As we known that the value of solubility constant of ferric hydroxide at is,
Amount or solubility of iron consumed = (1.800 - 0.3) mg/L = 1.5 mg/L
The given solubility of iron convert from mg/L to mol/L.
The chemical reaction will be:
The expression of solubility constant will be:
Now put all the given values in this expression, we get the concentration of hydroxide ion.
Now we have to calculate the pOH.
Now we have to calculate the pH.
Therefore, the pH will be, 3.2
