Strontium hydroxide octahydrate is an inorganic compound composed of strontium, hydroxide ions, and eight molecules of water. It is commonly used in chemical synthesis, refining processes, and materials research, and appears as a colorless or white crystalline solid.
The chemical formula of strontium hydroxide octahydrate is Sr(OH)₂·8H₂O. This indicates it consists of one strontium ion, two hydroxide ions, and eight water molecules of hydration.
The strontium hydroxide octahydrate melting point is approximately 100°C (212°F). At this temperature, the compound typically loses its water of hydration and begins to decompose.
The boiling point of strontium hydroxide octahydrate is not sharply defined because it decomposes upon heating before reaching a true boiling point. It gradually loses water molecules and converts to anhydrous strontium hydroxide at elevated temperatures.
What is strontium hydroxide octahydrate chemical typically used for? It is used in metallurgy, laboratory reagents, and the stabilization of polymers and plastics. Its strong basic nature also makes it valuable in neutralization reactions and pH control.
