Is dissolving of salt physical change or a chemical change?
The dissolving of salt in water is a physical change because it does not result in a chemical reaction. The salt molecules are simply breaking apart and becoming dispersed in the water, but there is no change in the chemical composition of the salt.
What is the chemical reaction between Epsom salt and water?
When Epsom salt (magnesium sulfate) is dissolved in water, it dissociates into magnesium ions (Mg2+) and sulfate ions (SO4 2-). This dissociation process is a physical change, not a chemical reaction, as the chemical composition of Epsom salt remains the same.
Is grinding salt a chemical or physical change?
physical
Is salt dissolved in water a chemical or physical change?
Dissolving salt in water is an example of a physical change. Although the ions of sodium and chlorine separate when the salt dissolves, no chemical reaction takes place.
What best describes the change in salt grains as they dissolve in water?
As salt grains dissolve in water, they break apart and the individual salt ions (sodium and chloride) become surrounded by water molecules, forming a solution. This process is a physical change, not a chemical reaction, as the chemical composition of salt remains the same.
Is possolving table salt in a glass of water a physical change of a chemical change?
It is a physical change because the chemical composition of the salt and water does not change.
Salt disappearing as it is stirred into a beaker of water is physical reaction?
No, the salt disappearing as it dissolves in water is a physical change, not a chemical reaction. This process involves the breaking of intermolecular forces between salt molecules, allowing them to mix and become distributed within the water. The chemical composition of the salt remains the same throughout this process.
Is cleaning a penny with vinegar and salt a physical or chemical change?
Cleaning a penny with vinegar and salt is a chemical change. The vinegar (acetic acid) reacts with the salt (sodium chloride) to form a chemical compound that removes the tarnish on the copper surface of the penny. This reaction changes the composition of the penny's surface, making it appear shiny and clean.
Is salting highways a chemical or physical change?
Salting highways results in a physical change because the salt dissolves in water to form a solution. This process involves a change in phase without altering the chemical composition of the salt itself.
Is mixing salt and water chemical?
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
What can identify salt?
The chemical composition, the crystalline structure, the taste, the melting and boiling point etc.
Is salt water a mineral?
No. a mineral is a compound of fixed chemical composition and of fixed crystal structure.
