Question

How does carbon dioxide react with the following? a) potassium b) Lime water c) sodium hydroxide​

Answer 1

Answer:

lime water

Explanation:

Answer 2

How does carbon dioxide react with the following?

1. potassium -

When Carbon dioxide react with Potassium then it form potassium carbonate.

4K + 3CO → 2K2CO3 + C

$\rule{200}2$

2. Lime water -

When Carbon dioxide react with Lime water then it turns milky due to the formation of calcium carbonate.

Ca(OH)2 + CO2 → CaCO3 + H2O

$\rule{200}2$

3. sodium hydroxide -

When carbon dioxide is react with sodium hydroxide then it is a neutralization reaction between acid and base which form to form sodium carbonate and water.

• Sodium hydroxide - Base
• Carbon dioxide - Acid
• Sodium carbonate - Salt
• water

Base + Acid ⟶ Salt + Water

2NaOH + CO2 → Na2CO3 + H2O
