Sulfuric Acid

Once of the first acids you'll ever make, and the first of many. Sulfuric acid is mandatory in MV , as it is needed to create Polyethylene, a basic plastic. However you can optionally make use of the acid in LV to make etching fluids.

How to make Sulfuric Acid

This is the first way that you will make sulfuric acid

In HV , after obtaining the LCR, you can make use of its chemical skips to do it all in 1 recipe, as seen bellow.

Later on, in ZPM, you can use the chemical plant instead.

You should definitely dedicate an LCR/Chem Plant to just making sulfuric acid. Having a dedicated storage (usually a fluid cell), is also recommended.

Alternate sources

Option 1: Hydrogen sulfide

You can react Hydrogen Sulfide with Oxygen in the LCR easily get some Sulfuric Acid. Its a good supplementary source if you happen to have some extra lying around.

Option 2: Smelting ores in the EBF for Sulfur Dioxide

There are a handful of ore dusts (Sphalerite, Pyrite, Galena, Stibnite, Tetrahedrite, Pentlandite, Cobaltite, Chalcopyrite), that when smelted in an EBF with Oxygen, produce a pure dust alongside Sulfur Dioxide.

Other options

There are a number of recipes that give sulfuric acid as byproducts. Not all of them are important or viable. A few examples of such recipes are:

• Sulfuric nickel solution electrolysis (See Platline)

• Triglycol Dichloride reaction

Among others.
