When sodium hydroxide dissolves in water, it undergoes a physical change as the sodium hydroxide molecules split apart into ions, which are then surrounded by water molecules. This process does not involve a change in the chemical composition of the sodium hydroxide molecule itself.
What else can I help you with?
Is physical or chemical reaction takes place when sodium hydroxide mixed with water?
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
Do sodium hydroxide dissolve fat grease and hair in a drain and is it a physical change or chemical change?
Yes, sodium hydroxide dissolves fat, grease, and hair in a drain by converting them into soap which can be washed away easily. This process involves a chemical change as sodium hydroxide reacts with the substances to break them down into different chemical compounds.
Is sodium hydroxide dissolve in water a chemical change?
Yes, when sodium hydroxide dissolves in water, it undergoes a chemical change as the ionic compound breaks down into its constituent ions (sodium and hydroxide) due to the interaction with water molecules. This process is known as dissociation and is a chemical change.
What ions form when sodium hydroxide dissolves in water?
When sodium hydroxide (NaOH) dissolves in water, it forms sodium ions (Na+) and hydroxide ions (OH-). The sodium ions are positively charged and the hydroxide ions are negatively charged.
When copper sulfate mixed with sodium hydroxide is a form of physical change or chemical change?
The reaction between copper sulfate and sodium hydroxide is a chemical change, as new substances are formed with different chemical properties from the original substances. The blue copper sulfate solution reacts with the colorless sodium hydroxide solution to form a blue precipitate of copper hydroxide and sodium sulfate solution.

When placed in H2O a sodium pellet catches on fire as hydrogen gas is liberated and sodium hydroxide forms chemical or physical change?
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.
What ions form when sodium hydroxide dissolves in water?
When sodium hydroxide (NaOH) dissolves in water, it forms sodium ions (Na+) and hydroxide ions (OH-). The sodium ions are positively charged and the hydroxide ions are negatively charged.
When copper sulfate mixed with sodium hydroxide is a form of physical change or chemical change?
The reaction between copper sulfate and sodium hydroxide is a chemical change, as new substances are formed with different chemical properties from the original substances. The blue copper sulfate solution reacts with the colorless sodium hydroxide solution to form a blue precipitate of copper hydroxide and sodium sulfate solution.
Is iron chloride and sodium hydroxide a physical or chemical change?
The reaction between iron (III) chloride and sodium hydroxide is a chemical change as new substances are formed. Iron (III) hydroxide and sodium chloride are produced as a result of the reaction.
What is the Name for NaOH?
The chemical name is Sodium Hydroxide. It is made of Na+ ions and OH- ions.
Is Sodium hydroxide dissolving in water a chemical or physical change?
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.
Is Reaction of hydrochloric acid with sodium hydroxide a chemical change?
Yes, the reaction of hydrochloric acid with sodium hydroxide is a chemical change. It forms water and sodium chloride, which are different substances with new chemical properties compared to the reactants.
When sodium reacts with water is it a chemical or a physical 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.
What kind of changes occurs when sodium chloride dissolves?
chemical change
