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.
When a sodium hydroxide dissolves in water is it a chemical change?
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.
When sodium hydroxide dissolve in water estimate the temperature change when the amount sodium hydroxide is doubled?
When sodium hydroxide dissolves in water, it undergoes an exothermic reaction, releasing heat. If the amount of sodium hydroxide is doubled, the same amount of heat will be released, resulting in an increase in temperature. The specific temperature change would depend on the initial amounts and concentrations of the sodium hydroxide and water.
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.

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.

What type of change is sodium hydroxide dissolving into water?
It is a physical change because no new substances are formed during the process of dissolving. Sodium hydroxide dissociates into its ions in water, but the chemical composition of the sodium hydroxide remains the same.
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.
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.
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.
Why is sodium hydroxide dissolving in water is a physical change?
Because the molecule of NaOH can be recovered unchanged from the solution.
