Why is acid added to water and not water to acid?
Mixing of acid with water is highly exothermic. Hence acid is added to water.Also, adding acid to water, if the mixture accidentally splashes you will be less likely to be injured by the dilute acid mix. Adding water to acid, if the mixture accidentally splashed you will be more likely to be injured by the still concentrated acid mix.
Is it dangerous adding water to concentrated sulphuric acid?
yes it is dangerous, becasue it will become warmer and then a exothermic reaction will happen hope this helped ;D
Example of exothermic?
When concrete cures it warms up. Those hand warmers that heat up when they are opened up are exothermic. Desiccants when exposed to a lot off water.
Which of the following is an example of an exothermic reaction?
does it matter? an exothermic reaction has heat as a biproduct of the product while an endothermic reaction has heat as a part of the reactants. meaning heat is released in exothermic and absorbed in endothermic
Why should water never drop-wise to concentrated sulfuric acid?
Adding water to acid releases heat and may cause the acid to splatter.

Pouring water into a concentrated battery acid dangerous?
Yes. Battery acid is sulfuric acid, and its dissociation in water is HIGHLY exothermic. Adding a small quantity of water to the concentrated acid releases so much heat that the water can reach its boiling point. Think frying bacon, except instead of hot grease spattering (which is bad enough) it's hot concentrated acid. Adding the acid to the water means that only a relatively small amount of acid is being added to a large quantity of water; this helps control the heat production (you should still do it carefully and slowly). "Do dilutions like you oughtta; pour the acid in the watta."

Is the neutralization of hydrochloric acid an exothermic or endothermic reaction?
ExothermicNeutralizing or even diluting a concentrated acid can be very exothermic. It can even cause the solution to boil if you are not careful! This is extremely dangerous! This is why when diluting concentrated acids (any kind) you should ADD ACID TO WATER and not the opposite.See the link below for more information about this important safety issue in the laboratory due to the exothermic nature of this reaction.
Safest way to dilute concentrated sulfuric acid?
Sulphuric acid should be diluted by adding acid to water while stirring continuously.
What happens when you mix water and sulphuric acid?
when we add water n sulphuric acid then dilute sulphuric acid is formed. But we have to mix concentrated acid to water not water to acid otherwise the container in which u r mixing may explode because this reaction is highly exothermic.
Is Hydrochloric Acid is a Exothermic?
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.
Is the reaction between MgO and 2HCl endothermic or exothermic?
Magnesium oxide is a very inert substance. It does not disolve readily in water but dos dissolve in acids. the reaction with concentrated hydrochloric acid is exothermic.
Why should acids and bases be handled carefully?
the process of dissolving an acid or a base in water is a highly exothermic one. care must be taken while mixing concentrated nitric acid or sulphuric acid with water. the acid must be added slowly to water with contant stirring.
