Write the chemical formula for the reactant which gives up a hydrogen ion in CaO + H2O Ca2+ + 2 OH-?

Question

write the chemical formula for the reactant which accepts a hydrogen ion in this reaction. What behaves like an acid in this reaction? Write the chemical formula for the reactant which behaves like a base in this reaction?

Answer 1

CaO + H2O ----> Ca2+ + 2OH-

If we're talking Bronston acids the:

CaO is the base, H2O the acid and on the other side of the equation Ca2+ is the conjugate acid (to CaO) and OH- is the conjugate base(to water)
