This is actually not a considered a chemical reaction but rather simply a dilution problem. Sodium hydroxide is considered a strong base and as such is able to completely and fully disassociate in aqueous solution. The heat evolved as a result of mixing solid sodium hydroxide with water is due to the the -OH ions incredible stability. heat is emitted as a result of the chemical species being brought to a lower energy state. This phenomena strong enough that sodium hydroxide crystals act as a powerful dessicant (it readily absorbs moisture from the air).
NaOH(s) +H2O(l)----------> Na(aq) + -OH(aq) + H2O(l)
also H2O can be found on both sides of this supposed "reaction" and thus cancel each other out
When an aldehyde reacts with sodium hydroxide, it can undergo oxidation to form carboxylic acids. This reaction involves the aldehyde group being oxidized to a carboxylic acid group in the presence of a strong base like sodium hydroxide.
CH3CHO + CH3CHO + NaOH ---> CH3CHO + NaCH2CHO --->CH3CHOHCH2CHO ---> CH3CH=CHCH=O is produced by this basic aldol reaction.
Step 1 is proton removal by the base
Step 2 is attack of the methylene carbanion on a nearby aldehyde, forming the 3 hydroxy butanal, which may dehydrate in Step 3 to form the alpha,beta unsaturated aldehyde 2-butenal
Additional anion formation at the same carbon before dehydration could lead to addition of another hydroxyethyl group, and after dehydration, the hydrogen on C4 becomes labile, so that small polymers are possible. There are other side reactions.
With the presence of an aldehyde and sodium hydroxide, an aldol condensation reaction will occur forming an aldol, and eventually an enal.
Yes it does. The caustic deprotonates the methanol to form methoxide. It is used by biodiesel manufacturers to transesterify triglycerides to make biodiesel.

What is the word equation for the reaction of sulfuric acid and sodium hydroxide?
The word equation for the reaction of sulfuric acid and sodium hydroxide is: sulfuric acid + sodium hydroxide → sodium sulfate + water.
What is sodium acetate made?
Sodium acetate is typically produced by the reaction of acetic acid with sodium hydroxide or sodium carbonate. This reaction forms sodium acetate and water. The compound can also be obtained from the reaction of sodium hydroxide with acetic anhydride.
Does water react with sodium hydroxide?
Yes, water reacts with sodium hydroxide to form sodium hydroxide solution (NaOH). This reaction is highly exothermic, producing heat.
What is a possible product of a reaction between chloromethane and sodium hydroxide solution?
One possible product of the reaction between chloromethane and sodium hydroxide solution is methanol and sodium chloride. Methanol is formed by the substitution of the chlorine in chloromethane with the hydroxide ion from sodium hydroxide, while sodium chloride is a byproduct of the reaction.
Explain what happens when sodium hydroxide solution is added to ammonium hydroxide?
When sodium hydroxide solution is added to ammonium hydroxide, a double displacement reaction occurs. Ammonium hydroxide is a weak base and sodium hydroxide is a strong base. The reaction produces water, sodium hydroxide, and ammonia gas.
What is the word equation for the reaction of sulfuric acid and sodium hydroxide?
The word equation for the reaction of sulfuric acid and sodium hydroxide is: sulfuric acid + sodium hydroxide → sodium sulfate + water.
What kind of reaction is ammonium nitrate and sodium hydroxide?
The reaction between ammonium nitrate and sodium hydroxide is a double displacement reaction, also known as a metathesis reaction. This reaction forms water, sodium nitrate, and ammonium hydroxide as products.
What type of reaction is sodium bromide mixed with calcium hydroxide?
The reaction between sodium bromide and calcium hydroxide is a double displacement or metathesis reaction. In this reaction, the sodium and calcium ions switch partners to form sodium hydroxide and calcium bromide.
What is sodium acetate made?

What causes the reaction between glucose solution and sodium hydroxide?
The reaction between glucose solution and sodium hydroxide is a chemical reaction that involves the hydrolysis of glucose molecules by the strong base (sodium hydroxide). This reaction results in the formation of sodium gluconate and water. The hydroxide ions from the sodium hydroxide cleave the glycosidic bonds in glucose molecules, leading to the breakdown of glucose into simpler compounds.
What happens in the reaction between sodium hydroxide and magnesium sulphate?
When sodium hydroxide reacts with magnesium sulfate, a double displacement reaction occurs where the sodium ions from sodium hydroxide switch places with the magnesium ions from magnesium sulfate to form sodium sulfate and magnesium hydroxide. The products of this reaction are aqueous sodium sulfate and a white precipitate of magnesium hydroxide.
Does gold react in sodium hydroxide?
Gold does not react with sodium hydroxide (NaOH) under normal conditions. Gold is a noble metal, which means it is relatively unreactive and does not easily form compounds with other elements, including sodium hydroxide.
What is the reaction of chloroform and sodium hydroxide?
The reaction of chloroform (CHCl3) and sodium hydroxide (NaOH) results in the formation of sodium trichloromethoxide (NaCCl3) and water (H2O). This reaction is a base-catalyzed halogen exchange reaction, where the chloride ion in chloroform is replaced by the hydroxide ion from sodium hydroxide.
What is the product of sodium hydroxide plus copper sulphate?
The reaction between sodium hydroxide and copper sulfate will result in the formation of sodium sulfate and copper hydroxide. The products of this reaction will be a blue precipitate of copper hydroxide and a solution of sodium sulfate.
