Understanding Calcium Oxide Soluble Properties

Calcium oxide (CaO) demonstrates exothermic solubility in water, achieving 1.73 g/100 mL at 20°C. This reactive compound transitions into calcium hydroxide (Ca(OH)₂) through hydrolysis, releasing 63.7 kJ/mol of thermal energy. Industrial-grade CaO typically maintains 92-98% purity, with particle sizes ranging from 5 µm to 2 mm influencing dissolution rates.

Technical Superiority in Manufacturing

Premium calcium oxide variants exhibit 15-20% faster reaction times compared to standard grades. Advanced calcination processes yield materials with:

• BET surface area ≥ 25 m²/g
• Reactivity onset < 45 seconds
• Residual carbonate content ≤ 1.2%

FAQS on calcium oxide soluble

Q: Is calcium oxide soluble in water?

A: Calcium oxide (CaO) reacts with water to form calcium hydroxide (Ca(OH)₂). It is not truly "soluble" but undergoes a chemical reaction. This process releases heat and creates a strongly alkaline solution.

Q: What happens when calcium oxide dissolves in water?

A: When calcium oxide mixes with water, it forms calcium hydroxide through an exothermic reaction. The resulting solution is sparingly soluble, leaving a milky suspension. This reaction is commonly called "slaking lime."

Q: Is calcium hydroxide soluble in water?

A: Calcium hydroxide has limited solubility in water (∼1.6 g/L at 20°C). It forms a weakly alkaline solution called limewater. Excess undissolved Ca(OH)₂ settles as a white precipitate.

Q: Why does calcium oxide appear to dissolve in water?

A: Calcium oxide doesn't dissolve but reacts chemically with water to produce calcium hydroxide. The heat released during this reaction can cause boiling. The final mixture is a suspension, not a true solution.

Q: How does the solubility of calcium oxide compare to calcium hydroxide?

A: Calcium oxide reacts completely with water, while calcium hydroxide has low solubility. Both form alkaline solutions, but CaO releases more heat during reaction. Neither compound is highly soluble in water.
