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!

When caustic soda (sodium hydroxide) is added to water, it undergoes a strong exothermic reaction where heat is released. The sodium hydroxide dissolves in the water, forming a strongly alkaline solution. This solution is commonly used in various industrial processes, such as water treatment and soap making.

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?
Acids are typically used to neutralize caustic soda. The reaction between caustic soda (sodium hydroxide) and acid will form water and a salt. Examples of acids commonly used for neutralizing caustic soda include hydrochloric acid, sulfuric acid, or acetic acid.
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".

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 happens when you mix caustic soda with sodium chloride?
Any reaction occur in this case.
Who owns Faygo soada?
National Beverage Corp.
Why it is advisable not to pick sodium with fingers?
It is advisable not to pick up sodium with bare fingers because sodium rapidly reacts with moisture in the air to form corrosive sodium hydroxide, which can cause burns or skin irritation. It can also result in hydroxide fumes that are harmful if inhaled, and the reaction can be vigorous enough to cause splattering.
What cleans valiums out of your system?
Water 1 galon- day. Mix in 1/2 teaspoon baking soada to neutralize the active ingred.
What will clean Valium out of your system?
Water 1 galon- day. Mix in 1/2 teaspoon baking soada to neutralize the active ingred.
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.
