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.
This is the degradation of a substance after the reaction with water.
hydrolysis: hydro = water, lysis = cutting
A chemical dryer works by absorbing moisture from materials through a chemical reaction. The dryer contains a substance that attracts and binds with water molecules, effectively removing moisture from the materials.
Because no new substance is produced
A reaction with water is a chemical process (or change); but reactivity is a property of a substance.
no. chemical reaction requires a new substance to be created
Neutralization always produces water, H2O (the 2 is actually a sub-script).
Hydration is a chemical reaction. It involves the addition of water to another substance.
A chemical reaction in which water or another simple substance is released by the combination of two or more molecules.
is the ease and speed with which an element combine,or reacts, with other elements and compoundsReactivity is known as a chemical substance. The chemical substance is what causes a chemical reaction.
No, mixing sodium polyacrylate with water is a physical interaction rather than a chemical reaction. The sodium polyacrylate absorbs the water, forming a gel-like substance, but no new chemical bonds are formed.
Dissolving in water is a physical change because the chemical composition of the substance remains the same. The particles of the substance are dispersed in the water but do not undergo a chemical reaction to form new substances.
