What is the effect on temperature of mixing sodium chloride with crushed ice?

Sodium chloride, or table salt, lowers the freezing point of water. The actual temperature will not be affected by adding salt outside of the normal heat exchange due to the surrounding environment. At room temperature, adding salt to crushed ice will begin to melt the ice because the water molecules will start to move quicker (turn to a liquid state) due to their freezing point lowering. This makes it an effective ice melter at temperatures at or just below the normal freezing point of water, 32°F or 0°C, with nominal amounts of salt. The actual lowered freezing point depends on the amount of salt added, but water will usually become supersaturated with salt when the freezing point reaches around -21.1°C.

Why is an increase in temperature observed on mixing chloroform with acetone?
The enthalpy of mixing for this mixture is negative: and the mixing is an exothermic process in this case.
Why is precipitation carried out by mixing slowly dilute solutions of barium chloride and sodium sulfate at a temperature near the boiling point?
Primarily to prevent inclusion of unreacted solution in the precipitate, which could easily occur if the solutions were concentrated, mixed too rapidly, or mixed at too low a temperature.

When can you withdraw heat from something without decreasing its temperature?
When it is a crushed ice water mix. As long as there is water remaining, and there is mixing flow between water and ice, the temperature will not decrease, but the ratio of ice to water will increase as you withdraw heat.
What would you do if you run out of crushed ice to be used a blend mixing method?
you'll going to use a muddler to crack and crushed ice
