Is Sodium hydroxide dissolving in water a chemical or physical change?
physical
What happens when you mix Disodium Phosphate with Sodium Hyrdroxide?
it makes a solution of sodium hydroxide, also called "caustic soda" or "lye" in dissolving, heat is produced - a lot of heat. always add sodium hydroxide to water --- NEVER water to sodium hydroxide (it can be explosive in mixing due to the heat) It should also be noted that the water should always be COLD. Adding sodium hydroxide to hot water will increase the exothermic reaction and result in dangerous spattering.
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)
Is the reaction between Sodium acetate and water a chemical reaction?
No, it is simply the water dissolving the sodium acetate, which is a physical change. There is a physical change when you introduce a seed crystal to the sodium acetate as the bonds in the chemical become different to form a solid. By adding water, you are just dissolving it and then allowing it to become supersaturated through heating.
What salt is made when sodium hydroxide reacts with hydroxide acid?
There is no reaction. "Hydroxide acid" is water, which does not react with sodium hydroxide.
Sodium hydroxide dissolve in water is physical change?
Yes, dissolving sodium hydroxide in water is a physical change.
Is Sodium hydroxide dissolving in water a chemical or physical change?
physical
Why is sodium hydroxide dissolving in water is a physical change?
Because the molecule of NaOH can be recovered unchanged from the solution.
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.
What is the balenced equation of dissolving sodium in water produces sodium oxide and hydrogen?
Sodium reacts with water to form sodium hydroxide and hydrogen. The balanced equation is 2Na + 2H2O --> 2NaOH + H2.
What is sodium oxide combines with water to make sodium hydroxide?
Sodium Hydroxide does not undergoes chemical change with water. It just becomes dilute or aqueous.
How is limewater formed?
Lime water is a solution of sodium hydroxide. Lime water is formed by dissolving calcium oxide, CaO or quicklime in water.
What is the constituent element of natrium?
Sodium. Pretty simple. Explosive metal, reacts violently with water, dissolving into sodium hydroxide (lye). NASTY stuff.
Is Sodium thiosulphate Dissolving in water physical change?
Yes. Dissolving is a physical change because it does not change the chemical composition of either the solute or the solvent.
What is the solubility of sodium in water?
Sodium doesn't dissolve in water, it reacts with water to form sodium hydroxide and hydrogen: sodium + water ----> sodium hydroxide + hydrogen

How will you change the aspirin to make it water soluble?
Usually by converting it to its sodium salt, by reaction with sodium hydroxide.
