In the reaction of acids lab, lime water (calcium hydroxide solution) changes due to the formation of calcium carbonate when carbon dioxide gas is produced by the acid reacting with a carbonate or bicarbonate. The reaction can be summarized as follows: when an acid is introduced, it reacts with the carbonate present, releasing carbon dioxide, which then reacts with calcium hydroxide in lime water to form the insoluble calcium carbonate. This results in a milky appearance, indicating the presence of carbon dioxide. The lime water's change reflects the acid-base reaction and the subsequent precipitation of calcium carbonate.
When water is added to quicklime (calcium oxide), it undergoes an exothermic reaction to form calcium hydroxide (slaked lime). This reaction releases heat, causing the lime to heat up. Additionally, the rapid formation of calcium hydroxide leads to an increase in volume, causing the lime to expand. This combination of heat and expansion can create a vigorous reaction, which is why caution is advised when adding water to quicklime.
If u add water to lime it will be lime water which is base thus when acid reacts with base then that will be "neutralization reaction". And formation of salt and water will take place. It will be exothermic in nature.
When water is added to lime-rock, a chemical reaction occurs, particularly with calcium carbonate (the primary component of lime-rock). This reaction can lead to the formation of calcium hydroxide, also known as slaked lime, which is a soluble substance. The process can result in a change in pH and the potential release of carbon dioxide gas. Additionally, the rock may begin to dissolve, altering its physical structure over time.
When water is added to lime (calcium oxide), a vigorous exothermic reaction occurs, producing calcium hydroxide, commonly known as slaked lime. This reaction releases heat and can cause the mixture to bubble and steam. The resulting slaked lime is a white, powdery substance that is alkaline and can be used in various applications, such as in construction or water treatment.
Any reaction occur.
The most common lime water reaction is with carbon dioxide, denoted by the equation: Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l) Since this is not a redox reaction (no oxidation numbers change), lime water is not an oxidizer.
When acids react with carbonates, carbon dioxide is produced. You can test this by waiting for the chemical reaction to take place and then using a bung to insert the gas into lime water!
When acids react with carbonates, carbon dioxide is produced. You can test this by waiting for the chemical reaction to take place and then using a bung to insert the gas into lime water!
When sulfur dioxide reacts with lime water (calcium hydroxide), calcium sulfite is formed. This reaction involves the neutralization of sulfur dioxide, leading to the formation of a white precipitate of calcium sulfite. This reaction is the basis for using lime water as a method to detect the presence of sulfur dioxide gas.
When limewater goes cloudy it means carbon dioxide is present!
Lime water is alkaline because it contains calcium hydroxide, which is a base. It is not neutral or acidic.
Lime water absorbs the carbon dioxide gas produced during the reaction
When lime (calcium oxide) reacts with water, it undergoes a hydrolysis reaction to form calcium hydroxide (slaked lime). This reaction is highly exothermic, releasing a large amount of heat. The resulting calcium hydroxide is a strong base and is often used in various industrial applications.

When hydrogen gas is passed through lime water, no immediate change will be observed. Lime water is a solution of calcium hydroxide, which is basic. Since hydrogen gas is neutral, it does not react with lime water to produce a visible change.
Lime water contains citric acid. So it is an acid substance.
Yes, adding lime (calcium hydroxide) to baking soda (sodium bicarbonate) results in a chemical change known as a double displacement reaction. The reaction forms water, sodium hydroxide, and calcium carbonate.
