In most cases, removing water is a physical change rather than a chemical change. This is often no more than a drying process where water evaporates from a substance.
However there are some chemical reactions that remove water from a substance. Of course, the substance itself will also change in this case. An example is copper sulphate. Its normal composition includes water (CuSO4 pentahydrate) but as it is heated, it loses water molecules and becomes CuSO4 trihydrate.

What is hydrolyzing a chemical?
This is the degradation of a substance after the reaction with water.
When liquid becomes a water vapor is that a chemical reaction?
no. chemical reaction requires a new substance to be created
Why is the boiling of water not a chemical reaction?
Because no new substance is produced
Is react with water is chemical change or property?
A reaction with water is a chemical process (or change); but reactivity is a property of a substance.
Differentiate between the reactants and the products in the reaction?
A reactant is an "ingredient" in a chemical reaction; it is a substance you have at the beginning of a reaction. A product is what gets produced in a chemical reaction; it is a new substance you did not have before. Reactants yield products.
Is Hydration a physical or chemical change?
Hydration is a chemical reaction. It involves the addition of water to another substance.
Is mixing water and baking soda a chemical or physical change?
chemical. when a reaction is undertaken that changes the structure of a substance and creates a new substance it is a chemical reaction. a gas is created during the reaction and a new chemical compound (sodium acetate) is left behind leaving neither of the previous elements present.
If one substance changes color is it a chemical reaction?
Not necessarily. Things sometimes change colors during a chemical reaction, but a color change is not sufficient evidence of a chemical reaction. You can add drink mix to water and the water turns colors, but it is not a chemical reaction, just a mixture.
What is condensation reaction?
A chemical reaction in which water or another simple substance is released by the combination of two or more molecules.
Sodium metal explodes when placed in water is this a physical property?
No, it is a chemical substance. The explosion is a violent chemical reaction.
Is boiling water a chemical or physical process?
Water boiling is a physical change and not a chemical reaction. In a physical reaction there is no new substance formed as is the case with chemical reactions. In boiling water there is no new substance produced.
What will happen to a rusty nail when its put into coke or other substance?
the nail will rust in water or any other substance that it is in by a chemical reaction
