What type of reaction is slaking of lime?

Thus, slaking of lime is an exothermic reaction. The reaction is carried out in slaking pits. The slaked lime or calcium hydroxide produced in this reaction dissolves in water and produces an alkaline solution which is known as limewater.

Is slaking of quicklime an endothermic reaction?

Formation of slaked lime from quicklime is an endothermic reaction.

Is heating limestone exothermic or endothermic?

When limestone is heated strongly, the calcium carbonate it contains absorbs heat (endothermic ) and decomposes to form calcium oxide.

Is quicklime an exothermic reaction?

Quicklime is not typically considered a fire hazard, but calcium oxide will react violently with moisture and give off heat (an exothermic reaction).

Which of the following is an example of an exothermic reaction?

An exothermic reaction is a chemical reaction that releases energy through light or heat and it is the opposite of the Endothermic reaction. Burning of natural gas, respiration, decomposition of vegetables into compost all are examples of exothermic reactions.

Is slaking of lime a combination reaction?

Slaked lime is only slightly soluble in water, so it forms a suspension of slaked lime in water. Calcium oxide and water react to form only a single product, calcium hydroxide. So the reaction is a combination reaction.

Which of the following is an example of exothermic reaction?

Which of the following processes are exothermic?

Exothermic reactions are chemical reactions that release energy as heat or light. A large amount of heat is released when quick lime reacts with water, along with the formation of calcium hydroxide. Similarly, the process of dissolving an acid or base in water is a highly exothermic reaction.

Is limestone exothermic?

Not all reactions are exothermic (or exoergic). The decomposition of limestone (CaCO3) to make lime (CaO) is also an endothermic process; it is necessary to heat limestone to a high temperature for this reaction to occur.

What is meant by slaking of lime?

The word slaking means the addition of water to calcium oxide powder (lime). The resulting product is calcium hydroxide (milk of lime). The reaction is exothermic, so the mixture heats up. Slaking is a key step in the most widely used procedure for formation of precipitated calcium carbonate.
