Is the dissolution of calcium hydroxide exothermic or endothermic?

Exothermic: Heat is given off as one of the products. The container holding the reactants and the products gets hot during the reaction. Use approximately 5 mL of 6M HCl and add to a testtube containing a small peice of mossy Zn. Immediately place a thermometer in the testtube and you will see a quick rise in temperature. This rise in temperature indicates that heat is given off which is a clear sign of an exothermic reaction. Hope this helps!!

∙ 13y agoAn exothermic reaction means heat is given out to the surroundings.
An endothermic reaction means heat is absorbed from the surroundings.
We do not say that a chemical, such as HCl, is exothermic or endothermic. The terms are used to describe the heat change involved in a reaction or process.

Is the dissolving of calcium chloride endothermic or exothermic?
Both beacuse in such coditions it can be endothermic or exothermic.
Would you describe the reaction of calcium in water as being exothermic or endothermic?
The reaction between calcium and water is very exothermic.
Does heating calcium carbonate produce an endothermic or exothermic reaction?
its an endothermic reaction, because the it broke the bonds of the calcium carbonate (CaCO3) in order to make calcium oxide (CaO) and Carbon dioxide (CO2).
Mix calcium oxide with water and then what happens?
Well, The chemical reaction when calcium is placed with water is a fizzing. It fizzes and also "produces" heat. Not sure what the chemical formula would be called however. Calcium Hydroxide possibly
When you add water to calcium oxide what does it give?
Calcium Hydroxide is the product when Calcium Oxide is reacted with water. It is an exothermic reaction liberating heat. This process is called slaking. CaO + H2O -----> Ca(OH)2.
Why is salt endothermic?
Not obligatory; the dissolution of sodium, calcium, potassium chlorides are exothermic.
Is the dissolving of calcium chloride endothermic or exothermic?
Both beacuse in such coditions it can be endothermic or exothermic.
Is obtaining lime from limestone exothermic?
The hydratation of concentrated OH- and Na+ ions (by dilution) is exothermic, it gives an energetically prefered state of matter.(Hydratation is the extra surrounding of the ions by polar water molecules of the solvent).
Would you describe the reaction of calcium in water as being exothermic or endothermic?
The reaction between calcium and water is very exothermic.
Is solid calcium carbonate with water an endothermic or exothermic reaction?
Yes.
What do you get when you add water to calcium oxide?
It's an exothermic reaction that produces calcium hydroxide.
Does phenol red mixed with calcium chloride and baking soda turn out to be a exothermic or endothermic?
it results in a exothermic reaction
Does heating calcium carbonate produce an endothermic or exothermic reaction?

Is an ionic compound exothermic?
A compound is never exothermic. Its reaction with some other substance is endothermic or exothermic like when calcium oxide reacts with water large amount of heat is evolved.

What is the reaction between calcium and water?
Calcium reacts with water to form calcium hydroxide and hydrogen gas. Calcium is oxidised and hydrogen is reduced, so it is a redox reaction. It is also a displacement reaction as hydrogen in water is displaced by calcium.
