the name is much different then the other
Compounds and solutions are pure substances
Solutions are mistaken for pure substances because they often appear uniform and have consistent properties throughout the mixture. However, solutions are actually a homogeneous mixture of two or more substances, where one substance (solute) is dissolved in another (solvent). This is different from a pure substance, which consists of only one type of particle.
If you mean pure substances then:HCl(aq) and NaCl(aq) are not pure substances but solutions. The (aq) means the substance is dissolved in water.HCl(g) and NaCl(s) is are pure substances
compounds
Pure substances (elements and compunds) and mixed substances (mixtures, solutions, alloys).
A pure substance has only one of atom or molecule. A mixture has a number of different pure substances mixted toghter.
no, solutions are not pure substances because all though they may look that way to the naked eye, the definition of a solution is a mixture where one substance has completely dissolved into the other. such as salt water. you can see only the water but you know the salt is there because when it dries out, the salt is left over.
No, silver is a pure element because it is made up of only one type of atom (Ag). It is not composed of different substances mixed together.
"Pure" generally implies that the object has no unwanted material. It can include mixtures and solutions. For example, Ivory soap is advertised as being 99.9% pure meaning it has nothing in it that they didn't intend to put in the soap.
Both pure substances and solutions have specific physical and chemical properties that are unique to their composition. Both can exist in different phases (solid, liquid, gas) and exhibit properties such as boiling point, freezing point, density, and solubility that are characteristic of their chemical makeup. Additionally, both pure substances and solutions can undergo physical changes such as melting, boiling, and dissolving without changing their chemical composition.
Some people divide matter into pure substances and mixtures. Pure substances are elements and compounds. Mixtures include homogeneous and heterogeneous mixtures. Some people divide matter into homogeneous matter and heterogeneous matter. Homogeneous matter includes pure substances and homogeneous mixtures (solutions). Heterogeneous matter is heterogeneous mixtures.
They are aqueous solutions of various compounds in water, so they consist of many separate pure substances. Many of these can be separated by simple physical means (filtering, evaporating, centrifuge).
