Final answer:
The pH of the solution will depend on the concentration of hydroxide ions. Since 1.3 XOH is soluble in water, it will dissociate into hydroxide ions. The concentration of hydroxide ions will determine the pOH and pH of the solution. The pH can be calculated using the equation pH = 14 - pOH.
Step-by-step explanation:
pOH is the negative logarithm of the hydroxide ion concentration in a solution. Since 1.3 XOH is soluble in water, it will dissociate into OH- ions. The concentration of hydroxide ions will determine the pOH of the solution. In pure water, the concentration of hydroxide ions is 1.0 × 10-7 M, so the pOH is 7.00. However, since the concentration of hydroxide ions in this solution is higher than 1.0 × 10-7 M, the pOH will be less than 7.00. Therefore, the pH of the solution formed will be the difference between 14 and the pOH.
Using the equation: pH = 14 - pOH, we can calculate the pH of the solution. Let's solve for pOH first.
pOH = -log[OH-]
Since the concentration of hydroxide ions is greater than 1.0 × 10-7 M, let's say it's X M. Therefore, pOH = -log(X)
Now, we can find the pH using the equation: pH = 14 - pOH. So, pH = 14 - (-log(X)).
