The reaction of sodium and water is considered to be a chemical change.
It is a chemical reaction for not only has the state changed of NaOH, but the identity of the substances have also changed.NaOH + H2O --> Na+ + OH-The "H2O" is not a reactant. It's actually supposed to go over the arrow. Sorry.Nonetheless, the dissolution of NaOH will increase the Hydroxide concentration, thus making it more basic. It will not change the identity of H2O.
The dissolving of sodium hydroxide in water is a physical change because no new substances are formed. Sodium hydroxide breaks down into its ions in the water, but its chemical composition remains the same.
Reactants: sodium (metal, Na) and water (H2O) Products: Hydrogen (gas, H2) and sodium hydroxide (NaOH)
This is a chemical change. When sodium reacts with water, it undergoes a chemical reaction to produce hydrogen gas and sodium hydroxide. The formation of new substances (sodium hydroxide) and the evolution of gas (hydrogen) indicate a chemical change rather than a physical one.
One example of a chemical containing hydroxide ions is sodium hydroxide, which has the chemical formula NaOH. When dissolved in water, sodium hydroxide dissociates into sodium ions (Na+) and hydroxide ions (OH-). Hydroxide ions are strong bases and can react with acids to form water and a salt.
Yes, They react to form sodium chloride, carbon dioxide, and water.
Yes, the reaction between sodium/potassium and water is a chemical change. This reaction produces hydrogen gas and hydroxide ions, resulting in the formation of a new substance with different properties than the reactants.
The chemical reaction of water with sodium is a chemical change.
Yea it is a chemical change. The Sodium reacts with water in a chemical reaction in which the sodium displaces the hydrogen in the water, creating sodium oxide and hydrogen gas. The heat from the reaction ignites the hydrogen, which creates the explosion.
That's most definitely a chemical change, because new forms of matter are produced. Before the reaction, you had pure sodium and water. After the reaction (which is very explosive by the way), you have sodium hydroxide and hydrogen gas.

chemical change
Sodium hydroxide and sodium sulfate don't actually react.
It does not react with water, but simply dissolves in it - a physical, not chemical, reaction.
chemical
A reaction with water is a chemical process (or change); but reactivity is a property of a substance.
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
