- Give clear handwritten solution- What is the normal boiling point of this compound? (Using phase diagram given)Consider the phase diagram below for Na, K, and the compound Na2K. For each region 1-6 give the number and identity of the phases present. Then describe the sequence of phase changes that would occur cooling of a solution of composition A (indicated on the diagram) to –30°C. Graph attachedWhy is it important to maintain the rock salt/ice mixture at a temperature of -10oC? A. Because it can be done B. Due to the limitations of the temperature probes or thermometers being used in lab. C. Because that is as cold as a salt/water mixture can get D. So all 3 solutions being measured will freeze
