Question
A solution reacts with crushed eggs shells to give a gas that turns lime turns milky.The solution contains?
Solution
The solution likely contains Hydrochloric Acid (HCl). Here's why:
- Eggshells primarily consist of calcium carbonate (CaCO3).
- When calcium carbonate reacts with hydrochloric acid, it forms calcium chloride, water, and carbon dioxide gas.
- The chemical reaction can be written as follows: CaCO3(s) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)
- The carbon dioxide gas produced in this reaction is what causes lime water to turn milky, as it forms a precipitate of calcium carbonate.
- Therefore, the solution that reacts with crushed eggshells to produce a gas that turns lime water milky likely contains hydrochloric acid.
