Question

Rahul prepared lime water freshly by mixing quicklime and water in a open beaker. He touched
the beaker and noted down his observation. What is the name of reaction between quick lime and

water? Is it exothermic or endothermic? If the beaker is kept open what will happen? Write two

chemical equations involved.

Answer 1

when quicklime and water reacts with each other It is double displacement reaction also it is exothermic as no heat energy is supplied from outside if the beaker is kept open for more time dissolution reacts with carbon dioxide or oxygen to form calcium carbonate
