| Mar 27, 2018 at 8:16 | comment | added | Klaws | The "other answer" would be...evolution. A species with a high enough concentration of acid in its body to explode when water is added would not survive. As mankind is not yet extinct[citation needed], we can assume that evolution has dealt with this and obviously found a way to mitigate this issue. Unfortunately, this answer belongs into Biology, not Chemistry. | |
| Mar 26, 2018 at 21:38 | comment | added | Karl | @RamKeswani I'm sorry, it is a shame how lousy textbooks (and teachers!) are especially in developing countries. You should never accept anything written in a book or said by a teacher if it is not satisfactorily, logically explained why and under what circumstances it is the case. | |
| Mar 26, 2018 at 20:19 | comment | added | zwol | @RamKeswani That sounds like safety advice for doing experiments. Safety advice is often much more cautious than is technically necessary. | |

| Mar 26, 2018 at 9:55 | comment | added | Ram Keswani | @Karl I study in India. The science book of mine (and of 70% other students in my age group) read, "You should add acid to water and not vice versa, because it results in an exothermic reaction and the contents of the beaker might splash out. The beaker might break." Only this much. Though not exact but nothing more. I am 15, and in class 10th. | |

| Mar 26, 2018 at 3:24 | comment | added | user545424 | There is an interesting video on YouTube exploring why it is recommended to add acid to water instead of vice versa: youtube.com/watch?v=fMYju7hMdqA. | |
| Mar 25, 2018 at 19:35 | comment | added | Oscar Lanzi | Right @Ian. I have experience with hydrochloric acid at work, for that one the big issue is fuming. I have found that if I add acid to enough water to drop the acid concentration to about 10%, then I can safely make up additional volume adding water. But upon water-rinsing the cylinder that contained 37% stock solution I see fumes from the traces of that acid. | |
| Mar 25, 2018 at 18:32 | comment | added | Ian | The point of the acid to water rule is to spread the acid around: a given mass of a given type of acid will make a certain amount of heat, and by having all the water already there, you give plenty of heat capacity to spread this heat around. But if there's not too much acid in the first place, then it doesn't matter. | |

| Mar 25, 2018 at 10:18 | comment | added | Alchimista | It is surely better to dilute acid by adding water and not viceversa. But it is not that all acids are H2SO4, as far "explosion" is of concern. Plus see answer | |
