Here's why:
* Strong Base: Calcium hydroxide dissociates completely in water, releasing hydroxide ions (OH-) which are responsible for the basic nature of the solution.
* Concentration Matters: The more calcium hydroxide you dissolve in water, the higher the concentration of OH- ions and the higher the pH value.
General Ranges:
* Saturated Solution: A saturated solution of slake lime at room temperature has a pH of around 12.4.
* Dilute Solutions: Dilute solutions of slake lime will have a pH lower than 12.4.
Important Note: It's challenging to give a precise pH value without knowing the specific concentration of slake lime in the solution.
If you need a more precise pH value, you'll need to:
1. Determine the concentration: Measure the amount of slake lime dissolved in a known volume of water.
2. Use pH calculations: Use the concentration of OH- ions and the appropriate formula to calculate the pH.
Let me know if you have more information about the specific slake lime solution, and I can help you determine a more accurate pH value.
