Question

Normally the maximum temperature of lime slaking is listed at about 100 C. I've read that using water with high salt concentrations will catalyze the slaking reaction and increase the boiling point thereby leading to higher slaking temperatures.

If you performed the slaking operation in a pressurized chamber this should increase the boiling point. Would it also lead to higher slaking temperatures

Answer 1

Adding salt to water increases its boiling point, leading to higher slaking temperatures in the lime slaking process. Performing slaking in a pressurized chamber further increases the boiling point of the solution, resulting in even higher temperatures.

Step-by-step explanation:

When salt is added to water, it increases the boiling point of the solution compared to pure water. This phenomenon is known as boiling point elevation. Therefore, if lime slaking is performed with water that has a high salt concentration, the boiling point of the solution will be higher than 100°C. Additionally, if the slaking operation is conducted in a pressurized chamber, it will further increase the boiling point of the solution, which will consequently lead to higher slaking temperatures.
