2/9/2003· The sulfuric acid solution reacts with calcium carbonate and calcium oxide forming calcium sulfates. Other forms of sulfuric acid can be used, such as oleum or fuming sulfuric acid. The use of this gypsum blend in Portland cement manufacturing with clinker is functionally equivalent to that of commercially mined gypsum currently employed by most Portland cement manufacturers.
Safety Precautions with Sulfuric Acid - Nsb Notes
As sulfuric acid is very exothermic (when dissolving in water), several safety precautions are taken with the handling, storage, dilution and transportation of sulfuric acid. Water placed in sulfuric acid is extremely dangerous, as the water completely ionises small amounts of water in concentrated amounts of sulfuric acid will boil and form an acidic mist which is highly acidic and damaging
Calcium Metal | ASSIST
Sulfuric or citric acid are not suitable for this purpose as they would give the much less soluble salts calcium sulfate and calcium citrate respectively. We recommend disposing of calcium by this method in small batches (10–20 g) of the metal, slowly adding this quantity of the metal …

Using Chemicals as Effective Drain Cleaners
It is not advisable to add sulfuric acid directly to water since it can cause spitting or splattering in the neutralizing process. However, the good news is that adding acid to water is safer than adding water to acid, so if this is for use in a toilet bowl or a sink full of water, it is reasonably safe.
