Salt lowers the temperature at which ice melts. Thus, it makes the temperature inside the cooler colder.
Putting salt on ice or snow decreases the melting point of water, a process known as freezing point depression. When salt is added, it disrupts the formation of ice crystals, causing the ice to melt at lower temperatures. This is why salt is commonly used to de-ice roads and walkways in winter.
The fastest way to cool a soda at a hot temperature is to place it in a bowl of ice water and add salt to the mixture. The salt lowers the freezing point of the water, speeding up the cooling process. Alternatively, you can place the soda in the freezer for about 15-20 minutes for a quick chill.
When you put ice in salt water, the salt lowers the freezing point of the water, causing the ice to melt. This process is known as freezing point depression. The ice absorbs heat from the surrounding water to melt, which makes the salt water colder than the original freshwater.
No one really invented it. For many years, salt has been known to lower the freezing point of water. This happens when the salt's ions dissociate in water. The act of lowering a freezing point (or raising a boiling point) is called water's colligative property. Generally speaking, the more ions in solution, the lower temperature at which water will freeze. The salt used on roads is usually calcium chloride (CaCl2).
The inventor of using salt to de-ice roads is not definitively known, but it is believed to have originated in the United States in the early 20th century. Initially, salt was used in small amounts, and its effectiveness in melting ice and snow led to widespread adoption for winter road maintenance.
Salt does not make ice cooler; it lowers the freezing point.
Pour salt on it; it will postpone melting.
The process of dissolving salt lowers the freezing point of the solution. So putting salt on the ice starts this process of dissovling, which creates a solution which will not freeze until a much lower temperature. Plain ice -- no solution.
salt does, because thats what i feel like putting down right now

To maximize the duration of ice retention in a cooler, you can use a high-quality cooler with thick insulation, pre-chill the cooler before adding ice, limit opening the cooler frequently, use block ice instead of cubed ice, and keep the cooler in a shaded and cool area.
It reduces the freezing point of water, therefore the water does not freeze until it gets a lot cooler.

Putting salt on ice lowers the freezing point of water, which causes the ice to melt. This process requires energy in the form of heat, so the surroundings, including the remaining ice, will get colder as the ice melts. In this sense, the ice will not freeze faster, but the overall system will become colder.
To keep ice in a cooler longer, you can try using a thicker cooler with better insulation, pre-chilling the cooler before adding ice, keeping the cooler out of direct sunlight, minimizing opening and closing the cooler frequently, and using larger ice blocks instead of smaller cubes.

Of course. Fresh water floats on salt water, warmer water floats on cooler water, and ice floats on any water.
