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.


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.


Water reacts with sodium metal to produce hydroxide and hydrogen gas along with heat and light sodium What are reactants in this chemical change?

Reactants: sodium (metal, Na) and water (H2O) Products: Hydrogen (gas, H2) and sodium hydroxide (NaOH)


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.


Chemical containing hydroxide ions?

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.


Is sodium and potassium react violently with water a chemical change?

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.


What is the chemical change of water?

The chemical reaction of water with sodium is a chemical change.


Is adding sodium to water 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.


When sodium is put into waterit react forming sodium hydroxide and hydrogen is this physical change or chemical change?

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.

If sodium bicarbonate reacts with water what is the result chemically?

It does not react with water, but simply dissolves in it - a physical, not chemical, reaction.

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.


Is dissolving sodium carbonate a chemical change?

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.
