Any impurity(something that does not belong to the compound but is present in the compound) has effects on the boiling and melting points of a given substance. From Yahoo answers,An impurity causes the melting point to deviate from the standard. Actually, it makes the magnitude of the melting point lower. For example, the melting point of benzoic acid is 122.4 degree Celsius. When we did this in the laboratory, we got 120 degree Celsius because of the impurity present which is sodium sulfate.An impurity also causes the melting point to become a melting range. The melting point is not anymore sharp, but a range of values. The more impurities present, the greater the range of values. For example, when we purified crude acetanilide via recrystallization, we obtained a melting range of 105-116 degree Celsius. By the way, the standard melting point of acetanilide is 113-115 degree Celsius.So basically, those are the two effects that impurities have on melting point iof a pre compound. I learned that it is because the impurities "defect" the crystal lattice of the compound. A pure compound is a structure of high molecular symmetry. An impurity is rather assymetrical, or is a poorly organized structure. If the impurites are present with the pure compound, the melting point will deviate because melting point is also dependent on the high symmetry and organization of molecular structures, just as the vapor pressure. This is the principle involved in Sublimati
An ice cube melts faster in salt water.
Adding salt to ice lowers its freezing point, which speeds up the melting process. This makes ice melt faster when salt is added compared to ice without salt. The exact time it takes for an ice cube to melt will depend on factors such as the amount of salt added, temperature, and size of the ice cube.
Salt water will melt an ice cube faster than flour water. This is because salt lowers the freezing point of water, causing the ice to melt more quickly. Flour water does not lower the freezing point significantly, so it will melt ice at a slower rate.
yes.
Yes it does, in northern states when it snows they use ice to melt the streets.
salt
Salt would melt the ice cube faster because if you have noticed, people put down salt to melt the ice.
yes as the salt dissolves lowering the ices freezing point!!
The ice cube made of salt and water will melt faster than the one made of sugar and water, which in turn will melt faster than the one made from just water. Salt and sugar lower the freezing point of water, which causes the ice to melt faster.
Ice cube with salt. The salt disrupts the lattice formation in the ice, lowering the melting temperature. As the salt melts ice, the surface area exposed to the salt increases, further perpetuationg the reaction.
an ice cube with salt
The time it takes for a 1-inch cube of ice to melt with one spoon of mineral rock salt can vary depending on factors such as the temperature of the environment and the specific properties of the salt. In general, adding salt to ice lowers its freezing point, causing it to melt faster. It typically takes a few minutes for the ice cube to fully melt with the addition of salt.
