Is the reaction between sodium hydroxide and benzoic acid exothermic?
yes.
The structure of the product when benzoic acid react with sodium hyroxide?
When benzoic acid reacts with sodium hydroxide, the carboxylic acid group (-COOH) on benzoic acid will undergo a neutralization reaction with the sodium hydroxide to form sodium benzoate salt and water. Sodium benzoate is a white, crystalline solid that is water-soluble. The reaction is a typical acid-base neutralization reaction, producing a salt and water as the products.
How prepare sodium benzoate?
To prepare sodium benzoate, you can neutralize benzoic acid with sodium hydroxide. This reaction forms sodium benzoate and water. The resulting sodium benzoate can then be purified through crystallization for use as a preservative in food and beverages.
Reaction of benzoic acid with sodium bicarbonate?
When benzoic acid reacts with sodium bicarbonate, it results in the formation of sodium benzoate, carbon dioxide gas, and water. This reaction is an example of an acid-base reaction where the benzoic acid (acid) reacts with sodium bicarbonate (base) to form sodium benzoate (salt) and carbon dioxide gas.
Why does sodium benzoate react with hydrochloric acid?
Sodium benzoate is a salt of a weak acid (benzoic acid). In water, sodium benzoate hydrolyses to form a strong base (sodium hydroxide) and benzoinc acid. This is an equilibrium reaction. Benzoic acid being a weak acid is only partially ionized in water whilst sodium hydroxide is fully ionoized. The resultant solution is therefore alkaline since the concentration of hydroxyl ions is greater than the concentration of hydrogen ions. The addittion of hydrochloric acid results in an acid base reaction formating a salt (sodium chloride). Since the addition of hydrochloric acid removes the sodium hydroxide, it forces the equilibrium to the right forming more benzoic acid which is precipitated.

What 2 substances will be formed when hydrochloric acid reacts with sodium hydroxide?
HCl + NaOH = H2O + NaCl Or, water and table salt--which will dissolve in water. Benzoic acid, C6H5COOH, will not be formed; neither of the two starting chemicals contains carbon, and benzoic acid contains a lot of it. - - - - - Benzoic acid and sodium chloride
Where does sodium benzoate come from?
Sodium benzoate is manufactured by reacting benzoic acid with sodium hydroxide. Benzoic acid is produced by partial oxydation of toluene with oxygen. There are half a dozen ways or more ways to make toluene.
What is the product when dissolve benzoic acid in dichloromethane and add sodium hydroxide?
The solvent (if it is entirely a solvent, as it is in this case) makes no difference. In theory, you would get sodium benzoate, but getting sodium hydroxide to react in a system including an organic solvent will not be easy as it is barely soluble. Vigorous agitation would be required.
What is the product of benzoic acid reacting with NH2?
benzoic acid + Sodium Hydroxide ==> water + sodium benzoate
Why is it necessary to extract ether layer with sodium hydroxide when reacting benzoic acid with hydroxide ion?
It depends on the overall reaction. If the carboxylic acid is an impurity in the reaction (undesired), then washing with sodium hydroxide will extract the carboxylic into the aqueous layer, and it can then be disposed. The reaction for this looks as follows: (ring)-COOH + NaOH -> (ring)-COO-Na+ + H20 Where the ring loses a proton to the hydroxide ion and becomes water soluble.
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.
Is benzoic acid react with sodium bicarbonate?
Yes, benzoic acid will react with sodium bicarbonate to produce sodium benzoate, carbon dioxide, and water. This reaction can be used to extract benzoic acid from a mixture as it is relatively insoluble in water but soluble in sodium bicarbonate solution.
