When carbon dioxide gas is bubbled through a solution of lithium hydroxide, lithium carbonate and water are produced. This reaction is utilized in carbon dioxide scrubbers to remove carbon dioxide from the air in closed environments such as spacecraft or submarines.
Sodium and carbonate ions typically do not form a solid precipitate when combined in solution, as both are usually soluble in water. However, they can form a white precipitate of sodium carbonate if carbon dioxide gas is bubbled through the solution, leading to the formation of insoluble sodium bicarbonate, which then decomposes to form sodium carbonate and water.
When carbon dioxide is bubbled through lime water, the lime water turns milky due to the formation of calcium carbonate, a white precipitate. This is a common test for the presence of carbon dioxide gas.
X is an acid. The acid reacts with Calcium Carbonate producing carbon dioxide. When this is bubbled through limewater, it produces a fine calcium carbonate precipitate giving a milky appearance to the limewater.
The precipitate formed is Calcium Carbonate (CaCO3).
When carbon dioxide gas is bubbled through a solution of lithium hydroxide, lithium carbonate and water are produced. This reaction is utilized in carbon dioxide scrubbers to remove carbon dioxide from the air in closed environments such as spacecraft or submarines.
When hydrogen sulfide gas is bubbled through a solution of iron III chloride, it forms iron III sulfide as a solid precipitate. This reaction is represented by the chemical equation: FeCl3 + 3H2S -> Fe2S3 + 6HCl.
Sodium and carbonate ions typically do not form a solid precipitate when combined in solution, as both are usually soluble in water. However, they can form a white precipitate of sodium carbonate if carbon dioxide gas is bubbled through the solution, leading to the formation of insoluble sodium bicarbonate, which then decomposes to form sodium carbonate and water.

Calcium carbonate, formula of this: CaCO3
X is an acid. The acid reacts with Calcium Carbonate producing carbon dioxide. When this is bubbled through limewater, it produces a fine calcium carbonate precipitate giving a milky appearance to the limewater.
You will see a preciptate of Calcium Carbonate [CaCO3] The Calcium Hydroxied is said to turn 'Milky' or 'Chalky' The chalkyness so described is the water insoluble Calcium Carbonate being deposited as it is formed.
Hydrogen.
In the experiment of anaerobic respiration of yeast, the yeast ferments sugars and produces carbon dioxide as a byproduct. When carbon dioxide is bubbled through lime water (calcium hydroxide solution), it reacts to form calcium carbonate, which causes the lime water to turn cloudy. If a hydrogen carbonate indicator solution is used, the increase in carbon dioxide leads to a color change, typically becoming more acidic and resulting in a shift in color depending on the pH change. This indicates the production of carbon dioxide during yeast fermentation.
The precipitate formed is Calcium Carbonate (CaCO3).
Hydrogen iodide can be tested using silver nitrate solution. When hydrogen iodide is bubbled through silver nitrate solution, a yellow precipitate of silver iodide is formed. This confirms the presence of iodide ions in the sample.
Lime water turns turbid when carbon dioxide (CO2) from the air is bubbled through it because the CO2 reacts with calcium hydroxide (the primary component of lime water) to form calcium carbonate (CaCO3). This calcium carbonate is insoluble in water and precipitates out, causing the solution to become cloudy or turbid. The reaction can be summarized as: Ca(OH)2 + CO2 → CaCO3 + H2O. Thus, the cloudiness is a result of the formation of solid calcium carbonate.
