when salt dissolves in water, the Na and Cl ions seperate, and chemical change is when any new substance is formed so arent like sodium ions or chlorine ions considered new substances (dissolving is meant to be a physical change?)?
sorry still dont get it

It breaks down into its molecules in the liquid. If you put salt in a glass of water, the salt is still in there, it has just separated into its ions, Na+ & Cl- (Sodium & Chloride), which are not visible to the naked eye.

salus has hit the best point. physics is the path to chemistry. understand what properties cause the chemical phenomena.Also a big hint to understanding many science aspects, simplifed versions are rarely leteral!

When a substance dissolves, it does not disappear, it is still within the solution. You just don't see it because it ionized. Take table salt, for example. The sodium and chlorine atoms break apart when in water, so you don't see the salt anymore, but it didn't disappear.

It fits into the spaces between molecules of the solvent, or it binds to molecules of the solvent. Take salt, for example. In aqueous solution sodium chloride dissociates into positive sodium ions and negative chloride ions. Because the water molecule is bipolar, a sodium or chloride ion can stick to it.

it is mixed together with whatever it dissolves in. Some part goes to air and some part goes to the water in like Alka Seltzer.

As long as it turns into chocolate milk, I'm good to go!

it dosnt dissaper,it is desolved,that means the paritcals of the matter have sepperated so much that you cant see them anymore.its all still there,its just so spread out and separated that you cant see it

it doesn't disappear it just breaks down into very small particle that are hard to see

Matter can never be dstroyed, only changed into another form.

It becomes part of whatever it disolves into-air, water, alcohol etc.
