A solution does not have a chemical change, but it does have a physical change in state.
it is a chemical change
If there is no chemical reaction occurring in the solution as a result of heating then this scenario constitutes a phase change.
Dissolving is a physical change.
Mixing sugar with iodine solution is a physical change because no new substances are formed. The sugar and iodine solution retain their individual chemical properties even when mixed together.
Because the salt solution is monophasic; filtering is applied when a precipitate exist.
A solution is a material not a change; dissolving is a physical process.
A chemical change is when the molecules of an object / solution are changed. A physical change is when the object / solution is altered without molecular change. Breaking glass is a physical change.
Chemical, When something changes in color, it is a sign of a chemical change.
Dissolving
When you combine them it is a chemical reaction (change) yes, but them combined in a solution is a 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
Mixing bread with iodine solution to observe a color change is a physical change as it does not alter the chemical composition of the bread or the iodine solution. The color change occurs due to a physical interaction between the starch in the bread and the iodine molecules.
