Applications can be found in the chemical industry, in scrubbers, but also in the in-situ extraction of minerals. There are many chemical processes in which concentrated sulfuric acid (H2SO4) must be diluted to the required concentration.

There are many chemical processes in which concentrated sulfuric acid (H2SO4) must be diluted to the required concentration. When it comes to sulfuric acid, dilute sulfuric acid is stronger than a concentrated one. Dilute the solution to 1.0 liter. This Standard Operating Procedure (SOP) gives a detailed method for how to dilute concentrated sulfuric acid. Safe mixer with good temperature control. Usually these systems dilute 98% or 93% sulfuric acid to lower strengths such as 70%, 50%,30% or lower using city water, RO water, or DI water.

For example, to make 100 mL of .01 molar (M) hydrochloric acid, use 10 mL of .1 molar acid and 90 mL of water.

In the example above, fill a flask with about 150 mL or more with distilled water, add 6.9 mL of concentrated sulfuric acid, then continue to dilute with water to the 250 mL mark.) Any strength lower than the strong acid can be produced. You will need to calculate what volume of the concentrated acid that contains 12.25 grams of sulfuric acid.

All those protons in solution would keep HSO4- from dissociating to makesulfate,SO4-2. When sulfur-containing fuels such as coal or oil are burned, sulfur dioxide is the main byproduct (besides the … Applications can be found in the chemical industry, in scrubbers, but also in the in-situ extraction of minerals. However the word "dilute" means that the H2SO4 is dissolved in water, so it is a mixture. Pour 3.7 mL concentrated sulfuric acid into 500 mL distilled water. Sulfuric acid itself is a compound with the formula H2SO4. Diluting concentrated sulfuric acid is an exothermic reaction. Sulfuric acid dilution & blending systems may be referred to as a sulfuric acid in-line-mixing system or an in-line-blending system.

Sulfuric acid is a strong acid, meaning that the first proton dissociates entirely and 1M H2SO4 has a [H+] of 1 M and pH of 0. Heat produced from dilution is removed by a heat exchanger, and the diluted sulfuric acid can be cooled to the designated temperature rapidly. 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 . Users should also consider risks and safety measures in their local environment before proceeding.

Diluting concentrated sulfuric acid is an exothermic reaction.

; It is considered safe to work with because it is designed inline. Dilute sulfuric acid is a constituent of acid rain, which is formed by atmospheric oxidation of sulfur dioxide in the presence of water – i.e., oxidation of sulfurous acid. Not only is the heat of dilution a big issue, but it will also eat any metallic material you intend to use in contact with it.
