The time it takes for saltwater to freeze in a 25ml volume would depend on the temperature of the freezer. Generally, saltwater freezes at a lower temperature than pure water, so it may take longer to freeze completely. However, a small volume like 25ml would likely freeze relatively quickly compared to a larger volume.
Salt lowers the freezing point of water, meaning it needs to be colder for the salt water to freeze compared to pure water. The salt itself does not freeze because its freezing temperature is much lower than that of the salt water solution.
If the salt is still in the water it will freeze inside the water so its technically frozen
Pure water freeze faster.
No, adding more salt to water actually lowers the freezing point, causing the water to freeze faster. This is because the salt disrupts the formation of ice crystals, making it harder for the water to freeze.
Salt water freezes at a lower temp than fresh, meaning colder. It may freeze faster when chilled enough be cause the salt would disrupt the plateo of the water so it may freeze faster.
Salt water takes longer to freeze than plain water because the salt lowers the freezing point of the water. The time it takes for either to freeze depends on the temperature of the environment and the concentration of salt in the water. Generally, plain water will freeze faster than salt water in the same conditions.
Water will freeze faster than salt water.

Salt water freezes at a lower temperature than regular water, so it will take longer for salt water to freeze compared to pure water. The exact time can vary based on the salt concentration, but generally, salt water will take longer to freeze due to its lower freezing point.
no salt water does not freeze faster than sugar.

Salt water will.
It depends on how you're trying to freeze them, of course: if you have a freezer that goes to 0 degrees F, like the one in the back room of a supermarket, it'll take as long to freeze the salt water as it would plain water. (Salt water has a lower freezing temperature than plain water but if you have a cold-enough freezer, it'll freeze.) If you pour it into liquid nitrogen, it'll freeze instantly. It also depends on the temperature of the salt water at first. Also, which type of salt, and how pure the water is. It also depends on the concentration of salt.
Yes, salt water does indeed freeze. The addition of a solute (salt in this case) to a solvent (water) will always lower the solution's freezing point. This just means it needs to be colder than 32oC to freeze the salt water.
