mixing strong acids and water generates a lot of heat. if you add a small amount water to a really strong acid, that water will quickly heat to boiling point & vaporize. the quick vaporization of water poured into the acid will cause the acid to blow out of the container and possible onto to you causing acid burns. by adding small amounts of acid to water, the excess water absorbs the heat of mixing and prevents blow out from the container.

Because a lot of heat is released during the acid-water interaction, it is an exothermic process. This heat turns some water into steam, which can splatter acid on our faces or clothes, resulting in acid burns. When diluting an acid, it is preferable to introduce the acid to the water rather than the other way around. Because adding water to a concentrated acid generates a lot of heat, it can explode and cause acid burns on the skin, clothes, and other body parts. As a result, whereas mixing acid with water is safe, mixing acid with water is not.

∙ 9y agoThe addition of water to acid produces an exothermic reaction producing heat. It is important that a small amount of acid is slowly added to water to regulate the heat exchange.

∙ 15y agoAdding acid to water must be done slowly because it is an extremely exothermic reaction. Thus, large amounts of energy in the form of heat are given off if you add acid to water too quickly.

Large water add to small acid?
Never add water to an acid always add small amount of acid slowly in large amount of water.
Why do you put acid in water?
If you add acid to water, the water slowly turns into a dilute solution of acid. If you add water to acid, it creates a large amount of heat (exothermic reaction), which can be very dangerous.
How do you add the acid?
if the acid is hygroscopic like concentrated sulphuric acid then always add acid into to water but not water into acid if u want to dilute the acid because the liquid bumps and may injure the worker....
What are the Laboratory techniques on mixing water and acid?
Mixing water and acid is very exothermic. Potentially enough heat is generated to cause the water to instantly vaporize, which can result in splattering (and messing up any volume calculations you may have already done). For this reason, ALWAYS add acid to water, NOT the other way around. The water acts as a heat sink and can absorb any heat that is generated. For best results, add the acid slowly while gently swirling the flask/beaker of water. You can also submerge the water flask/beaker into an ice bath.
What happens if you mix sulfuric acid with water?
Acid is acid; if you put water in acid, no biggy, just liquid, but if you put acid in water... it's gonna blow. DON'T LISTEN TO THIS IDIOT! Always, always, always add acid to water as a precaution, but ESPECIALLY with sulphuric, which is extremely hydrophylic and produces an exothermic reaction, otherwise you'll be going to hospital and then the plastic surgeon. Slowly adding the acid to water will ensure that the acid dilutes in the larger volume of water and that the ratio of acid to water is always low and the water is able to disperse the heat and you don't get a runaway reaction. If you really do need to dilute some concentrated sulphuric acid, the safest way is to freeze the amount of water you need and pour the acid over that. I'm sorry, but if this is typical of the level of intellectual input on this site then don't do any serious research here, use wikipedia instead.
Large water add to small acid?
Never add water to an acid always add small amount of acid slowly in large amount of water.
If one wants to top up a tank of muriatic acid should one first add the water or concentrated acid?
When mixing acid and water, always add the acid to the water, and add it slowly. Never add the water to the acid.

Do you add water to acid or add acid to water?
you add acid to water
How do acid reacts with water?
You should always add (small parts of) the concentrated compound (acid, hydroxide) to (the larger amount of) water, because you can stirr and mix and cool down better (heat of hydration can be absorbed much better by the water and surroundings)

Can you add water to sulphuric acid?
Yes, you can. You can also tug on Superman's cape, spit into the wind, and pull the mask off the old Lone Ranger. None of these are good ideas. Never add water to acid, always add acid to water.
When dissolving acid into water always add?
Do dilutions like you oughta:Add the acid to the wata. Yes, it's cheesy. But you should always pour the (concentrated) acid into the water, not the other way around.

When mixing acid and water how do you add the acids to the water?
Because mixing acid and water is usually a VERY exothermic process there are two things which ought to be done: 1) Add the acid to the water (rather than water to the acid). As I can tell you from personal experience when I grabbed a beaker of sulphuric acid instead of the intended glacial acetic acid and tried to pour water into it, the heat of the mixing process can be sufficient to boil the water that is being added. (My little mistake prompted a rather quick trip to the sink to flood my arm with cold water to get rid of the acid and keep the thermal burns to 1st degree rather than 2nd degree as well as some careful cleanup of the boiled over acid/water mixture) 2) as you add the acid to the water it helps to have a cooling source to absorb all that heat being produced by the mixing process.
How do you make 25 percent sulfuric acid from 98 percent sulfuric acid?
Take 1 ml of 98% acid and add to 3 ml of water to get 25% acid. Total volume will be 4 ml (in this case). You can scale up this to any volume you need. (always add acid to water and not water to acid)
