Question

5. When carbon dioxide is passed through lime water, * 1 point A.) Calcium hydroxide is formed B.)lime water turns milky C.) Colour of lime water dissappear D.) None Other:​

Answer 1

Answer:

• Calcium hydroxide is formed

Carbon dioxide reacts with limewater (a solution of calcium hydroxide, Ca(OH) 2), to form a white precipitate (appears milky) of calcium carbonate, CaCO 3. Adding more carbon dioxide results in the precipitate dissolving to form a colourless solution of calcium hydrogencarbonate.

Answer 2

Answer:

B) Lime water turns milky  is correct

Explanation:

When CO₂ gas is passed through freshly prepared lime water then lime water turns milky

CO₂ (g) + Ca(OH)₂ (aq) ⇒ CaCO₃ (s) + H₂O (l)
