MAGNESIUM OXIDE
MgO demonstrates controlled hygroscopicity, absorbing up to 35% moisture by weight in humid conditions. This "breathing" property is leveraged in humidity buffers and food packaging desiccants. Upon exposure to water, it undergoes a sluggish hydration reaction to form Mg(OH)₂, releasing 317 kJ/mol heat-useful in self-heating materials but requiring careful storage. The oxide's surface exhibits Lewis basicity (pH ~10.5 in slurry), making it ideal for acid gas (e.g., CO₂, SO₂) chemisorption.
