This reaction is dangerous, especially at home, as lithium immediately burns with a bright flame: Warning! Don’t try to repeat this experiment without a professional supervision! Here you’ll find safe experiments for doing at home. If a small piece of lithium is added to concentrated sulfuric acid, lithium sulfate, hydrogen sulfide and water form. Reaction of lithium and sulfuric acid The alkali that forms in the solution is called lithium hydroxide LiOH, which consists of white crystals, and is quite a strong base: The reaction of the dissolution of lithium in water is accompanied by a characteristic hissing. Like all alkaline metals, if lithium is placed in water, an alkali begins to form, and hydrogen is released, and the metal floats on the surface and literally melts before your eyes. The reaction takes place quite calmly. This property means that lithium does not even sink in kerosene. But it is also interesting that compared with its “alkaline neighbors”, lithium has the lowest density – half the density of water. It is interesting that lithium is the only metal from this group which boils and melts at rather high temperatures: 1340 and 180.54 degrees Celsius respectively. It is soft and easily molded, and a cube of metallic lithium can be cut with a knife. Lithium is an alkaline metal of a silvery-white color. This is far from all the spheres where this metal and its compounds are used. Lithium is vital for human health in small amounts, and takes part in the functioning of vital organs such as the heart, liver and lungs. Lithium salts are widely used in medicine. Lithium is also used in radio electronics and nuclear energy Lithium is often used as a metal for alloys, making it possible to create light but durable solders
