Referring to salt being added to crushed ice perhaps? When this is done, the salt causes the ice to melt. Melting actually requires heat (latent heat of liquifaction) and so the melting ice draws heat from its surroundings, thus lowering the temperature of its surroundings. A mixture of crushed ice and salt is frequently used in the laboratory and referred to as "freezing mixture".

What one of the compounds below is most likely to be ionic?
Sodium chloride is most likely to be ionic. Ionic compounds are formed between a metal and a nonmetal, and sodium is a metal while chloride is a nonmetal. Additionally, sodium chloride is a common example of an ionic compound.
What is salts solubility?
Salt (sodium chloride) is highly soluble in water. It dissolves readily in water due to its ionic nature, breaking down into positively charged sodium ions and negatively charged chloride ions. This solubility makes salt a commonly used substance for seasoning and preserving food.
Which compound below is an example of a binary ionic compound?
Sodium chloride (NaCl) is an example of a binary ionic compound. It forms between the metal sodium (Na) and the nonmetal chlorine (Cl).
How many milliliters of a 1.00 M solution of sodium chloride are needed to completely react with 100 grams of water according to the chemical reaction shown below?
There is no chemical reaction between sod chloride solution and water, it would just dilute the sod chloride solution.
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.
Is sodium chloride a solid liquid or gas?
Sodium Chloride is the scientific name for table salt. It is a solid because room temperature (at a normal dinner table) is far below its melting point.
What is the hazard symbol for sodium chloride?
Sodium chloride hasn't a hazard symbol or a risk phrase. See also the link below.
Where will you find a MSDS for sodium chloride?
See the link below.
Hardness of sodium chloride?
Sodium Chloride IS hard, just brittle, that's why it breaks apart in your hands. The hardness of sodium chloride is 2,5 on the Mohs scale.
Why is sodium chloride used to make freezing mixtures used by ice cream vendors?
Sodium Chloride when added to water helps reduce the freezing temperature of water, meaning that water will stay liquid at temperatures below it's actual freezing point of 0 degrees Celsius. Similarly, when sodium chloride is added to ice, the temperature of the mixture reduces rapidly and helps keep things cooler and ice creams are best when they're cold :) Hope this helps.
What is the freezing point depression of sodium chloride?
The maximal freezing point depression for sodium chloride is -18 0C. For the theoretical calculus see the link below.
What one of the compounds below is most likely to be ionic?
Sodium chloride is most likely to be ionic. Ionic compounds are formed between a metal and a nonmetal, and sodium is a metal while chloride is a nonmetal. Additionally, sodium chloride is a common example of an ionic compound.
What are some uses of sodium chloride?
Sodium chloride (NaCl) is table salt.Flavoring condiment for food,Food preservative,Lowers freezing temperature of water. Can melt ice on roads, also used in making ice cream by helping the salt water to remain liquid and drop to temperature below 0° Celsius.There are other uses of the chemical properties of sodium chloride salt, including water softening systems, as well as many industrial applications.
What is salts solubility?
Salt (sodium chloride) is highly soluble in water. It dissolves readily in water due to its ionic nature, breaking down into positively charged sodium ions and negatively charged chloride ions. This solubility makes salt a commonly used substance for seasoning and preserving food.
What does salt do to plastic?
Sodium chloride doesn't react with plastic materials. See the link below.
What is the arrangement of atoms in sodium chloride?
Sodium chloride forms a lattice structure.
Is sodium chloride a green house gas?
Sodium chloride, like most everything else, can exist in any of the three states. Considering standard pressure, it exists as a gas above 1465°C, which is very hot, but possible. It is a liquid between 801-1465°C. It is solid at all temperatures below 801°C. The melting point is so high because ionic bonds are the strongest type of intermolecular forces.
