NaOH gives Na(aq.) and OH-(aq).....
the heat of formation for sodium hydroxide is -425.6 kJ/mol (so it's exothermic).
When you dissolve NaOH in water, the reaction is exothermic. But this is dissociation, the opposite of formation. So logically, you would flip the sign around for the heat of formation to get the enthalpy change of the dissociation, right? But if you do, the enthalpy change becomes +425.6 kJ/mol, which means that it is endothermic. However, the dissolving of NaOH in water releases heat to the environment, so it's exothermic!

How do acids react with caustic soda?
Acids typically react with caustic soda (sodium hydroxide) to form water and a salt. The acid donates a proton (H+) to the hydroxide ion (OH-) in caustic soda, resulting in the formation of water (H2O) and a salt specific to the acid used. This reaction is known as neutralization.
Who is chemical neutralized caustic soda?
A strong acid would do. We will show sulfuric acid doing this. 2NaOH + H2SO4 -> Na2SO4 + 2H2O The reaction produces a slat, sodium sulfate, and water and is called a neutralization reaction.
What is the percent water in 10 BE Caustic?
10 BE Caustic typically contains around 54-65% water.
What air makes colorless caustic potash turn milky?
Carbon dioxide gas reacts with caustic potash (potassium hydroxide) to form potassium carbonate, which is insoluble in water. This reaction produces a milky or cloudy appearance in the solution.
What is the name given to a reaction the gives off energy?
A reaction that gives off energy is an exothermic reaction. The reaction will give off energy in the form of either heat or light An example of an exothermic reaction would be the curing of concrete. One chemical reaction that will give off heat is the mixture of Caustic Soda and water. The water dissolves the Caustic Soda which in turn generates heat. There are two types of reactions. Exothermic reactions give off heat, and endothermic reactions require that heat be added to make them work. Be careful with exothermic reactions. A rapid, energetic exothermic reaction is called an "explosion".

What is the white stuff formed at the bottom when caustic soda is mixed with water?
The white stuff formed at the bottom when caustic soda is mixed with water is typically sodium hydroxide crystals. These crystals result from the exothermic reaction that occurs when caustic soda dissolves in water, causing the solution to heat up and potentially precipitate solid sodium hydroxide.
What is the percent water in 10 BE Caustic?
10 BE Caustic typically contains around 54-65% water.
A sentence for caustic?
Caustic can mean sarcastic or scathing or it can mean able to burn organic tissue by chemical reaction. The solution was caustic enough to burn through clothing. Her caustic comments made the other girl feel bad.
What air makes colorless caustic potash turn milky?
Carbon dioxide gas reacts with caustic potash (potassium hydroxide) to form potassium carbonate, which is insoluble in water. This reaction produces a milky or cloudy appearance in the solution.
What is the reaction when anhydrite is exposed to caustic soda?
When anhydrite (calcium sulfate mineral) is exposed to caustic soda (sodium hydroxide), a reaction may occur where the sodium from the caustic soda can replace some of the calcium in the anhydrite, forming sodium sulfate and calcium hydroxide. This reaction is often used in industrial processes for desulfurization or for the production of sodium sulfate.

Descriptively what reaction is caused by mixing 98 percent concentration sulfuric acid 50 percent concentration caustic soda?
Mixing 98% concentration sulfuric acid with 50% concentration caustic soda will result in a highly exothermic reaction, releasing significant heat energy. This reaction will generate sodium sulfate, water, and heat as products. It is important to handle this reaction with caution, as it can lead to the release of noxious fumes and cause burns if proper safety precautions are not taken.
