Question

What is colemanite ? What happen when of colemanite react with sodium carbonate ?​

Answer 1

hi dude

colemanite means a white crystalline mineral, typically occurring as glassy prisms, consisting of hydrated calcium borate.

Colemanite react with sodium carbonate and water

2Ca2B6O11 + 4Na2CO3 + H2O → 3Na2B4O7 + 4CaCO3 + 2NaOH

Colemanite react with sodium carbonate and water to produce sodium tetraborate, calcium carbonate and sodium hydroxide.

Answer 2

When colemanite react with sodium carbonate it forms calcium carbonate.

Explanation:

• Colemanite is an important ore of boron.
• Colemanite is a hydrated calcium borate which is a white crystalline occurring as a glassy prism.
• It is having a monoclinic crystal.
• It is a borate mineral which is found as an evaporite mineral.
• Colemanite react with sodium carbonate In this colemanite is powdered and is boiled with sodium carbonate,where it forms calcium carbonate.

$Ca2B6O11+2Na2CO3------2CaCO3+X Na2B4O7+Y 2NaBO2$

• It has many industrial uses such as heat resistant glass.
