a. When the gas formed on heatinglimstone is passed through freshlyprepared lime water, the lime waterturns milky |
| Answer» <p>Here is the answer----</p><p>The Gas formed on heating limestone is Carbon dioxide. When this gas is passed through lime water, it forms Calcium Carbonate or limestone which turns milky.</p><p>Reaction for the above is---When Limestone is heated, CaCO₃ --------Heat------- CaO + CO₂.(limestone)</p><p>When Carbon Dioxide is passed through lime water,</p><p> CO₂ + Ca(OH)₂ ------------- CaCO₃↓ + H₂O. (lime water)</p><p>Reason ⇒When Carbon dioxide is passed through Lime water or Calcium Hydroxide, it turns milky due to the formation of the Precipitate of the insolublemilky Calcium Carbonate.</p> | |
