I'd think that it is a chemical change... Mixing NaCl(Sodium Chloride) with AgNo3(Silver Nitrate) in aqueous states is simple precipitation... unless u're talking about mixing the powders by themselves?
Mixing Epsom salt and ammonia would result in a physical change. It is considered physical because no new substances are formed during the mixing process.
Yes, adding silver nitrate to salt water would cause a chemical change as it would result in the formation of a white precipitate of silver chloride, indicating a chemical reaction has occurred.
No, mixing sodium carbonate and copper sulfate is a physical change as the substances retain their chemical identities. A chemical change would involve a reaction where new substances are formed.
The reaction between water and concrete is a chemical change because new substances are formed as a result of the mixing process. In this case, the components of the concrete react with the water to form a new compound that hardens into a solid material through a chemical reaction.

Physical
It depends on what you are mixing it with.
it is a chemical change
physical :)
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.
both chemical and physical
A simple mixing is a physical process.
