Sr(HCO3)2, or strontium bicarbonate, is a chemical compound composed of strontium, hydrogen, carbon, and oxygen. It typically appears as a white solid and is soluble in water, where it dissociates into strontium ions and bicarbonate ions. Strontium bicarbonate is often encountered in geological and environmental contexts, as it can form in natural waters containing strontium and carbon dioxide. Additionally, it has applications in various fields, including chemistry and materials science.
