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.

Why is slaked lime added to water after chlorination?
Slaked lime is added to water after chlorination as a coagulant to destabilize the electrostatic charges of suspended particles in the water.
What is added to quicklime to make slacked lime?
Water is added to quicklime the make slaked lime. Calcium hydroxide reacts with water to form calcium hydroxide. CaO + H2O --> Ca(OH)2
What is the effect carbon dioxide in lime water?
Lime water turns milky when carbon dioxide is added to it.Lime water also turns into Calcium carbonate (Limestone) solution
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 effect of the gas oxygen on lime water?
When oxygen gas is added to lime water (a solution of calcium hydroxide), it reacts with the calcium hydroxide to form calcium carbonate, which is white and insoluble in water. This reaction causes the lime water to turn milky.
Why is slaked lime added to water after chlorination?
Slaked lime is added to water after chlorination as a coagulant to destabilize the electrostatic charges of suspended particles in the water.
What is the color of lime water when phenolphthalein is added into lime water?
The color is pink with phenolphthalein.
Does lime make water alkaline when added to it?
Yes, lime can make water alkaline when added to it. Lime, also known as calcium hydroxide, has a high pH level, which can raise the alkalinity of water when it is dissolved in it.
What happen when Water Is Aded To Lime?
When hydrogen is added to lime water, the solution becomes milky. This is because it forms calcium carbonate.
What is added to quicklime to make slacked lime?
Water is added to quicklime the make slaked lime. Calcium hydroxide reacts with water to form calcium hydroxide. CaO + H2O --> Ca(OH)2
What happen when quick lime is added water?
It reacts with water to form calcium hydroxide.
What happens when cherry juice is added to lime water?
the colour will change
Which gas is evolved when acid is added to lime water?
When an acid is added to lime water (calcium hydroxide solution), carbon dioxide gas is evolved. This reaction forms calcium carbonate, which is insoluble in water and appears as a white precipitate.
What happens when turmeric solution is added to lime water?
Turmeric become brown.
What is the effect carbon dioxide in lime water?
Lime water turns milky when carbon dioxide is added to it.Lime water also turns into Calcium carbonate (Limestone) solution
Why is lime added to acidic lakes?
Lime is a strong base. When you add a base to an acid it turns it neutral. So by adding the lime to the water after a while it'll turn into precipitation itself and neutralize the acid. This is also known as acid-base neutralization.
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.
