Why does lime expand and get hot when water added to lime?
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.
What type of reaction takes place between lime and the acid?
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.
What happens if sodium hydroxide is mixed to the lime water?
Any reaction occur.
what is a correct observation when water is added to lime?
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.
What is the purpose of using lime water during the reaction of the acid sample with marble chip?
Lime water is used during the reaction of the acid sample with marble chips to test for the presence of carbon dioxide. If carbon dioxide is produced during the reaction, it will react with the lime water to form a white precipitate of calcium carbonate, confirming the presence of carbon dioxide in the acid sample.
Is lime water an oxidizer?
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.
What happens when acid react with compounds made of carbonate?
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!
What happens when acids react with compounds of carbonates?
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!
What kind of reaction occurs when sulphur dioxide reacts with 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.
What gas does lime water change into?
When limewater goes cloudy it means carbon dioxide is present!
Is lime water an acids alkali or neutral?
Lime water is alkaline because it contains calcium hydroxide, which is a base. It is not neutral or acidic.
What is the purpose of using lime water during the reaction of the acid sample with the marble chip?
Lime water absorbs the carbon dioxide gas produced during the reaction
What happens when lime reacts with water?
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.
What happen when acids react with carbon?
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!
Is lime water alkali?
Lime water contains citric acid. So it is an acid substance.
What happens when hydrogen gas is passed through lime water?
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.
How did the exercising change the time needed for the lime water to change?
it happened cause the time needed for the lime water to change was made less
