Being exothermic relates to a reaction of two substances which give out heat to the surroundings. As such, hydrochloric acid can't be exothermic by itself.
If you add concentrated hydrochloric acid to water, however, heat is generated in the reaction which is one of the reasons why hydrochloric acid should only be diluted in this way (acid added to water, not the other way round) otherwise the solution can quickly and violently boil over and cause acid and heat burns to anything it touches.
What else can I help you with?
Is hydrochloric acid and copper carbonate exothermic?
Yes, the reaction between hydrochloric acid and copper carbonate is exothermic. This means that it releases heat during the reaction.
Is the reaction of sodium bicarbonate with hydrochloric acid endothermic or exothermic?
The reaction of sodium bicarbonate with hydrochloric acid is exothermic. This is because heat is released during the reaction as the chemical bonds are broken and new bonds are formed.
Is reacting calcium carbonate with hydrochloric acid endothermic or exothermic?
Reacting calcium carbonate with hydrochloric acid is an exothermic reaction. It releases heat energy as the reaction proceeds, making the surroundings warmer.
Is this endothermic or exothermic when a antacid tablet reacts with hydrochloric acid?
The reaction of an antacid tablet with hydrochloric acid is typically exothermic, meaning it releases heat. This is because the reaction between the tablet and acid produces energy in the form of heat.
Is hydrochloric acid dissolving in water an exothermic reaction?
Yes, the dissolution of hydrochloric acid in water is an exothermic reaction because it releases heat energy. This is due to the formation of hydrogen ions and chloride ions from the dissociation of the acid molecules.

Is reaction between hydrochloric acid and aluminum endothermic or exothermic?
The reaction between hydrochloric acid and aluminum is exothermic because it releases heat as the products are formed. This reaction produces hydrogen gas and aluminum chloride.
When hydrochloric acid neutralizes sodium hydroxide the temperature increases is this exothermic or endothermic?
When the temperature increases as a result of reaction, as specified here, the reaction is exothermic.
What is the enthalpy change when hydrochloric acid reacts with magnesium?
The enthalpy change when hydrochloric acid reacts with magnesium is exothermic, meaning it releases heat energy.
What is the enthalpy change when magnesium reacts with hydrochloric acid?
The enthalpy change when magnesium reacts with hydrochloric acid is exothermic, meaning it releases heat energy.
A strip of zinc is dropped into a test tube of hydrochloric acid?
an exothermic reaction
When silver nitrate reacts with hydrochloric acid the container gets warmer is this reaction exothermic or endothermic?
This reaction is exothermic because it releases heat energy. The reaction between silver nitrate and hydrochloric acid generates a salt and releases heat as a byproduct.
When zinc reacts with dilute hydrochloric acid does the temperature of the acid increase or decrease?
The temperature of the acid increases when zinc reacts with dilute hydrochloric acid because the reaction is exothermic, meaning it releases heat.
