Ca(OH)2 + 2HCl ===> CaCl2 + H2O
a) True
b) False; neutralization
c) True
d) True. In the neutralized solution of CaCl2, Ca+2 + H2O ===> CaOH+ + H+. This is called hydrolysis. Because Ca(OH)2 is a weak base (slightly soluble) and HCl is a strong acid (completely ionized), the pH will be a little less than 7.

Statements a, c, and d are correct.
The reaction equation is
Ca(OH)2 + 2HCl = CaCl2 + H20
As you see the reaction produces water and CaCl2 which is a salt,
Two molecules of HCl are needed per molecule of
Ca(OH)2 and
The pH will be below 7, because we have the salt of a weak base and a strong acid.
