limewater. in A Dictionary of Chemistry (6) Length: 73 words. 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)+CO2 (g) → CaCO3 (s)+H2O (l) If the carbon dioxide continues to be bubbled through, the calcium ...
A chemical equation represents a chemical reaction. It shows the reactants (substances that start a reaction) and products (substances formed by the reaction). For example, in the reaction of hydrogen (H₂) with oxygen (O₂) to form water (H₂O), the chemical equation is:
