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.

Will you use hot water or cold water in order to dissolve maximum amount of lime for white wash of the house?

To dissolve the maximum amount of lime for whitewashing a house, hot water is preferable. Hot water increases the solubility of lime, allowing it to dissolve more effectively than cold water. This results in a smoother mixture, which can enhance the application process and overall finish of the whitewash.


When water is added to lime it expands and gets extermly hot what can you tell from this?

The reaction between water and lime is exothermic, meaning it releases heat. This is due to the chemical reaction that occurs when water reacts with lime to form calcium hydroxide. The expansion is a result of the heat generated in the reaction causing the water to evaporate and create steam.


Do liquids expand?

Yes. liquids expand. If we heat the beaker which is filled with water using a candle, the volume will rise as the water is mixed with hot air. Hot air would want to excape, therefore liquids do expand.
