When you first start to bubble carbon dioxide through limewater (calcium hydroxide solution), they react and form calcium carbonate. This isn't very soluble, so you see it as a mist of fine particles of chalk, which we describe as 'the limewater has gone cloudy/ milky'. As you continue to bubble, carbon dioxide dissolves in the water to form carbonic acid, which dissolves the calcium carbonate, so the milkiness disappears. Here are the reactions: Ca(OH)2 + CO2 --> CaCO3 + H2O forming the milkiness 2H2CO3 + CaCO3 --> Ca(HCO3)2 + H2O +CO2 removing the milkiness again This second reaction is the same one as for rainwater flowing over limestone rocks.

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.
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 magnesium is mixed with lime water?
When magnesium is mixed with lime water, no immediate reaction occurs. The white precipitate that forms when lime water reacts with carbon dioxide in the air will not form when magnesium is added.
How is slake lime made?
adding water to quick lime produces slaked lime.
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 happen when quick lime is added water?
It reacts with water to form calcium hydroxide.
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 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 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 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.
