limewater

Chemistry

A saturated solution of calcium hydroxide in water. When carbon dioxide gas is bubbled through limewater, a ‘milky’ precipitate of calcium carbonate is formed:
${Ca (OH)}_{2} (aq) + {CO}_{2} (g) \to {CaCO}_{3} (s) + H_{2} O (1)$
If the carbon dioxide continues to be bubbled through, the calcium carbonate eventually redissolves to form a clear solution of calcium hydrogencarbonate:
${CaCO}_{3} (s) + {CO}_{2} (g) + H_{2} O (g) \to {Ca (HCO}_{3})_{2} (aq)$
If cold limewater is used the original calcium carbonate precipitated has a calcite structure; hot limewater yields an aragonite structure.
