Question

reaction of quick lime with hydrochloric acid
​

Answer 1

Answer:

This reaction is highly exothermic (produces vigorous heat). If water (containing acid or not) is added in sufficient quantity, vapours, bubbles (due to boiling) and hissing sounds can be observed. Addition of acid, further increases the heat of the reaction.

Overall reaction: CaO + 2 HCl =CaCl2 + H2O

It is a double replacement (AB +DC = BC + AD) acid-base reaction.

CaO is a (Lewis) base. Hcl is a (Brønsted) acid. CaCl2 is a salt. In aqueous solution, HCl + H2O = H3O+ + Cl-

Formation of slaked lime from quick lime in an aq. form HCl, i.e.

CaO + H2O = Ca(OH)2 leads to further production of water soluble calcium chloride salt by this reaction: Ca(OH)2 +2 HCl = CaCl2 + 2 H2O

Answer 2

Answer:

When Calcium oxide reacts with Dilute Hydrochloric acid then it forms calcium chloride and water..

The Reaction are as follows::

CaO + 2HCl ==> CaCl2 + H2O

 Calcium oxide + Hydrochloric acid =>> Calcium chloride and water .
