A salt can be formed by several processes. You can synthesize a salt from its constituent elements. The equation for the synthesis of sodium chloride from its elements is 2Na+Cl2-->2NaCl. You can also synthesize salt in an acid/base reaction, which is form of double replacement where your products are almost always water and some kind of salt. Given reactant solutions of sodium hydroxide and hydrochloric acid, the equation is NaOH+HCl-->H2O+NaCl.
Both these processes are chemical changes, because you produce salt, a chemical compound, which you did not have before.
What else can I help you with?
Is the dissolving salt in water a chemical or physical change?
The dissolving of salt in water is considered a physical change, not a chemical change. This is because no new substances are being formed during the process; the salt molecules are simply breaking apart and dispersing throughout the water.
What type of change occurs when salt is mixed with water?
When salt is mixed with water, a physical change occurs. The salt dissolves in the water, forming a homogeneous mixture called a solution. The chemical composition of the salt and water remains the same.
Is salt forming a physical chance or chemical change?
It is a chemical change because the sodium(Na) is a liquid that forms with a yellow gas, chlorine(Cl), which changes the physical state to a dickmuncher solid, but ultimately they reacted with each other chemically to form salt (NaCl). It does change the physical state, but it is more of a chemical reaction.
What type of change when a substance changes into a new substance?
chemical
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.
Is a salt getting formed a chemical change or physical change?
I think it is a chemical change Forming underground it is a chemical change Salt forming from a saline solution for example h20 + NaCl --delta-> h2 + O2 + NaCl (This is not a balanced solution) This is a physical change, since there is no change to the Sodium Chloride
Is crystallization of salt a physical change?
Assuming you're talking about salt forming as water evaporates: yes, that is a physical change. If you mean salt crystals forming from the combination of sodium and chlorine, then that's a chemical change.
Is the dissolving salt in water a chemical or physical change?

Is mixing an acid and base to produce water and a salt chemical or physical change?
Mixing an acid and base to produce water and a salt is a chemical change because new substances with different chemical properties are formed. The reaction between the acid and base involves the breaking and forming of chemical bonds, resulting in the formation of water and a salt.
Is salt forming a physical chance or chemical change?

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 a cavity forming a physical or chemical change?
chemical
