Answer 1

Answer:

When you mix concentrated sulfuric acid and water, you pour the acid into a larger volume of water. ... Sulfuric acid (H2SO4) reacts very vigorously with water in a highly exothermic reaction. If you add water to concentrated sulfuric acid, it can boil and spit and you may get a nasty acid burn.
