What equipment used to separate salt water of the mixture magnet balance funnel or hot plate?
The equipment needed to separate salt water would be a funnel for filtration, a hot plate for evaporation, and a balance for measuring quantities accurately. A magnet would not be useful for separating salt from water, as salt is not magnetic.
Is water desalination a physical change?
Yes, water desalination is a physical change. It involves the separation of salt and other impurities from water using physical processes such as evaporation or reverse osmosis, without altering the chemical composition of water.
What happens when you add salt to water and how does it affect the properties of the solution?
When salt is added to water, it dissolves and breaks down into ions. This process is called dissociation. The presence of salt in water increases the boiling point and decreases the freezing point of the solution. It also increases the density and conductivity of the water.
Which of the following pieces of equipment should be used to separate a mixture of salt water magnet B balance C funnel D hot plate?
Look at each of the options and really think about what each one would mean and need. To separate a mixture of salt waterA magnet - There is no metallic substanceB balance - There is nothing to weighC funnel - A funnel can direct water away, but the salt is IN the water.D hot plate - If you heat a salt-water mixture, the water will evaporate, and the salt will crystallize and be left behind. So I would choose D.
What does physical properties mean in science terms?
Physical properties are things you observe with your eyes during chemical reaction e.g. Salt analysis the choking smell of ammonia u observed with your nose is a physical properties of ammonia
What are the steps to Separate a Mixture?
It all depends on the substance and its physical properties. For example, salt water can be separated by boiling the water and letting the salt remain.
Will salt keep its physical properties in water?
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.
What physical properties allows you to separate salt from water?
Salt can be separated from water based on differences in physical properties such as boiling point and solubility. When water is heated, it evaporates at a lower temperature (100°C) than the salt, which remains solid. This process, known as evaporation or distillation, allows the water to turn into vapor while leaving the salt behind. Additionally, since salt is soluble in water but not in steam, this further aids in their separation.
Why wont a magnet help you separate a mixture of salt and water?
A magnet is not effective at separating salt and water because salt is not attracted to magnets. The components in the mixture have different physical properties (magnetism for the magnet, solubility for the salt) that make it impossible to separate them using a magnet. You would need to use methods like evaporation or filtration to separate salt from water.
How can physical properties be used to separate iron sand salt and water?
Use a magnet to remove the iron, a filter or screen to remove the sand, and a still to remove the salt.
What physical properties are used to separate the mixture of sea water and salt?
That would probably depend on how you separate them. For example, if you want to use reverse osmosis, then the salt molecules don't go through the filter as easily as the water molecules - either because they are bigger or because of their electric charge.
Is dissolving salt in water 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.
Is salt dissolves in water a physical or a chemical?
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.
Is water and salt a physical change?
No, salt will (physically) dissolve in water, without changing chemical properties
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.
Dissolving salt into water is it physical or chemical change?
This is a physical change. You can separate the salt and water by the physical process of distillation or evaporation where the water is boiled away and the salt is left behind.
The rate of evaporation decreases when common salt is added to water why?
Solutes affect the physical properties of water.
