They have different properties because the element that make up these compounds are different, water is made up of 2 hydrogen atoms, and 1 oxygen while table salt is made of a sodium and a chlorine atom. These different combinations make up different properties. Why the elements that make up these compounds have different properties however is a different question.
They are composed of different kinds of element.
Salt water contain dissolved sodium chloride; chemical and physical properties are different compared with fresh water.
Any solution has different properties compared with a solvent. The composition is different.
When water is mixed with salt, the properties of the salt remain unchanged. However, the properties of the water may change, such as its boiling and freezing points. The salt dissolves in the water, forming a homogeneous solution.
Salt dissolves in water. The resultant liquid has higher density than pure H2O. Teh salt solution has less electrical resistance than pure water, it tastes different too. Depending on how much salt and how much water were mixed, some salt might remain undissolved (the mixture is saturated).
No, because ocean water is not salt. Ocean water does have salt dissolved in it, but there are distinct chemical and physical differences. First, ocean water is not crystalline while salt is. Second, ocean water is a solution with many different solutes while salt is a pure compound.
An alloy is similar to salt water in that both are mixtures of different substances that retain the properties of their individual components. Just as salt water consists of water and salt, where the salt dissolves but maintains its chemical identity, an alloy is made by combining metals to create a material with enhanced properties. In both cases, the resulting mixture has unique characteristics that differ from those of the individual components.
he properties of salts are different from the properties of elements that go into making them
No, salt will dissolve in water, breaking down into its ions. This process alters the physical properties of the salt as it no longer exists as solid crystals but instead as individual ions dispersed in the water.
Salt water has a much lower freezing point than fresh water. If freshwater is saturated with salt, the freezing point is minus 21.1 degrees celcius. The chemistry is complex, but in simple terms, saltwater becomes a different substance to fresh water, they have different chemical properties.
I think you mean are the properties of salt different from the elements that it is made up from. Sodium chloride is common salt that we put on our food. It has formula of NaCl amd is made up of the elemnts sodium and chlorine. Sodium is a highly rective metal that rects violently with water. Chlorine is poisonous gas at room temperature. So yes. This is a feature of compunds they often have very different properties from their constituent elements.
Salt water is a homogeneous mixture. Salt, however, is a compound. It has its own properties different from the original elements that created it. It was chemically combined and can only be separated by those means.
