Lithium, sodium, potassium, rubidium, and cesium (L-R). What are the hazards? Alkali metals react with air to form caustic metal oxides. The heavier alkali metals (rubidium and cesium) will spontaneously ignite upon exposure to air at room temperature.
What Are Sodium Nitrate and Sodium Nitrite?
Sodium nitrates (NaNO 3) and sodium nitrites (NaNO 2) are naturally occurring chemical compounds commonly used in cured meat products such as bacon and hot dogs. For home cooks, a product called "pink salt" or Prague powder that coines sodium nitrites and/or nitrates with sodium chloride (salt) makes it possible to safely preserve meat for flavor and extended storage.

What Are the Effects of Sulfuric Acid on Metal? - wiseGEEK
28/6/2020· The effects of sulfuric acid on metal depend on a nuer of factors, including the type of metal, the concentration of the acid, and the temperature. Dilute sulfuric acid will, in theory, react with any metal that lies above hydrogen in the reactivity series by displacing hydrogen from the acid, releasing it as a gas and forming the sulfate salt of the metal.
