When dry ice (solid carbon dioxide) is dissolved in water, it undergoes a physical change rather than a chemical change. The dry ice sublimes, meaning it changes directly from a solid to a gas without passing through the liquid phase. This process is reversible, as the carbon dioxide gas can re-solidify back into dry ice when the temperature decreases.
What else can I help you with?
Does physical change occur when epsom salt is dissolved?
Yes. The way I think about it is if you can change it back (in this case, you could filter the epsom salt out, or evaporate the water, drying it) then it is a physical change.
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.
What is the chemical formula for hydrochloric acid when it is dissolved in water?
The chemical formula for hydrochloric acid when dissolved in water is HCl.
What properties do not change when sugar is dissolved in water?
The chemical composition of sugar remains the same when dissolved in water. Only the physical state of sugar changes, from solid to liquid. The total amount of matter in the system (sugar + water) also remains constant.
Is the taste of salt in water a physical or chemical change?
Taste is due to chemical reactions in the mouth.
When salt is dissolved in water a is it a chemical change?
Physical
What type of change occur when sugar dissolved in water?
physical
Is dissolved salt in ocean water an example of a chemical change?
No. It is a physical change. All you have to do to separate the two is to evaporate the water. There is no chemical change.
Solid forms into dissolved water is a chemical or physical change?
Dissolving in water is a physical change.
Is dissolved salt in the ocean water an example of a chemical change?
No.
What is the chemical reaction occurring when you put sucrose and water together?
Any reaction occur; sucrose is dissolved in water.
Is orange juice physical or chemical change?
it is physical because there is no new matter will produce(( water+ juice dissolved)) just
What is a type of change that does not occur in the water cycle called?
A type of change that does not occur in the water cycle is the transformation of matter into a different chemical element. In the water cycle, water remains as H2O molecules throughout the various processes such as evaporation, condensation, and precipitation, without changing its fundamental composition.
Does physical change occur when epsom salt is dissolved?
Yes. The way I think about it is if you can change it back (in this case, you could filter the epsom salt out, or evaporate the water, drying it) then it is a physical change.
Dissolved salt in ocean water is an example of a chemical change true or false?
false
What chemical reaction occurs when sodium chloride is dissolved in water?
No chemical reactions occur because sodium only forms ions like chloride.
When a teaspoon of salt is dissolved In a pot of water will the salt undergo a chemical change or a physical change?
When a teaspoon of salt is dissolved in a pot of water, it undergoes a physical change. The salt dissociates into its constituent ions, sodium and chloride, but its chemical structure remains unchanged. This process is reversible, as the salt can be recovered by evaporating the water. Thus, the dissolution of salt in water is a physical change rather than a chemical one.
