What Are the Dangers of Sulfuric Acid? (with pictures)
2020/8/9· Sulfuric is a strong acid that is colorless, odorless, highly reactive, and soluble in water, and which has the potential to be quite dangerous when improperly handled. One of the best-known and most important dangers of sulfuric acid is its ability to cause severe burns when it comes in contact with skin.
Binding properties of alginic acid and chitin
to metal ions and metal alginates to iodine, cholesterol and dyes [1, 2], it became desirable to have experimental values for several measurements of granular alginic acid (H-alg.) obtained from the treatment with hydrochloric acid.
Hydrochloric Acid Safety Precautions | Sciencing
Hydrochloric acid -- or HCl -- is an acid that is highly corrosive when concentrated. Always handle it with care to prevent harm or injury. You need to take specific safety precautions when handling, transporting and storing HCl and get medical help immediately if
why is the reaction between calcium and sulphuric acid …
2009/5/24· Possibly because when calcium reacts with sulfuric acid the resulting calcium sulfate makes a poorly soluble coating on the calcium and hinders free access of the acid to the calcium surface. When calcium reacts with HCl, the calcium chloride is freely soluble and offers little or no protection of the calcium surface.
