What is the chemical equation for limestone?
Limestone consists of calcium carbonate, which has the chemical formula CaCO3.
How does limestone react?
When limestone is heated strongly, the calcium carbonate it contains decomposes to form calcium oxide. This reacts with water to form calcium hydroxide, which is an alkali . Calcium hydroxide dissolves in water to produce calcium hydroxide (limewater), which is used to test for carbon dioxide.
What kind of reaction is heating of limestone?
When limestone is heated in a kiln, the calcium carbonate breaks down into calcium oxide and carbon dioxide. This type of reaction is called thermal decomposition.
What is the formula of lime solution?
Ca(OH)2
Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca(OH)2. It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed or slaked with water….Calcium hydroxide.

What is the formula for limestone and lime?
These rocks are composed of more than 50 % carbonate minerals, generally containing the mineral calcite (pure CaCO3). Limestone is a sedimentary rock composed mainly of CaCO3….Limestone and Lime.

What happens if you burn limestone?
When limestone is heated strongly, the calcium carbonate it contains absorbs heat (endothermic ) and decomposes to form calcium oxide. This is indicated by an orange glow as the limestone is heated.
What happens when limestone dissolves?
The limestone dissolves to form a salt (in the chemical sense), water, and carbon dioxide.
Does limestone dissolve in rain?
Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide in the atmosphere forms very dilute carbonic acid when it dissolves in rain.
How will you classify the chemical reaction of obtaining quicklime from limestone?
So, when we strongly heat limestone then it decomposes to give slaked lime (CaO) and carbon dioxide. The chemical reaction equation will be as follows. Calcium oxide (CaO) is also known as quick lime. This reaction is a decomposition reaction.
What type of a reaction is respiration?
Respiration is a series of exothermic reactions that occur in the mitochondria of living cells in order to release energy from food molecules. This energy can then be used to produce heat, for movement, growth, reproduction and active uptake.
Is lime water acidic or basic?
It is basic in nature with a pH of 12.4. Limewater may be prepared by mixing calcium hydroxide (Ca(OH)2) with water and removing excess undissolved solute (e.g. by filtration).

What happens when you add calcium carbonate to limestone?
Open Yenka file Model 1. This is a simple experiment. Limestone can undergo a thermal decomposition reaction. When you are ready add the calcium carbonate (limestone) and start to heat it up. When the temperature of the tube reaches 400°C look in the reaction details to see the reaction that is happening.
What makes up the phases of the limestone cycle?
The limestone cycle. 1 Calcium carbonate. Calcium carbonate, calcium oxide and calcium hydroxide are all made from limestone and have important applications so it is 2 Calcium oxide. 3 Calcium hydroxide.
