May 17, 2020 · Sulfuric acid (H 2 SO 4) is the most dangerous common acid to dilute. Partly, this is because it reacts so violently with skin and clothing. Sulfuric acid quickly dehydrates proteins and carbohydrates in skin and muscle. The acid is much heavier than water, so water added to it reacts with the top layer first.

On a laboratory scale, sulfuric acid can be diluted by pouring concentrated acid onto crushed ice made from de-ionized water. The ice melts in an endothermic process while dissolving the acid. The amount of heat needed to melt the ice in this process is greater than the amount of heat evolved by dissolving the acid so the solution remains cold.
Nov 30, 2023 · The process described here can be used for hydrochloric, sulfuric, nitric, or phosphoric acid, but other acids may require further research to dispose of properly: Ventilate the area by opening windows and doors, and turning on fume hoods and fans.

Dilute sulfuric acid is a strong acid and a good electrolyte; it is highly ionized, much of the heat released in dilution coming from hydration of the hydrogen ions. The dilute acid has most of the properties of common strong acids. It turns blue litmus red.
Aug 17, 2019 · Sulfuric acid (H 2 SO 4) 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.

Jan 29, 2024 · For instance, battery acid, a familiar term for many, is essentially diluted sulfuric acid used in lead-acid batteries. Its composition is carefully calibrated to optimize the performance and longevity of these batteries, which power vehicles and store energy in backup power systems.
Jul 22, 2022 · A 1.50 mL aliquot of a 0.177 M solution of sulfuric acid (H 2 SO 4) is diluted into 10.0 mL of distilled water, to give solution A. A 10.0 mL aliquot of A is then diluted into 50.0 mL of distilled water, to give solution B .
