Neither, because it a salt of strong base(Calcium) and strong acid(Chloric acid)
Perchloric Acid
Calcium sulfate is a salt because it is formed from the reaction between a base (calcium hydroxide) and an acid (sulfuric acid). It is a neutral compound with a 1:1 ratio of calcium ions (from the base) to sulfate ions (from the acid).
Potassium Perchlorate
Ca-acetate is a weak base, conjugated with a weak acid: H-acetate (i.e. acetic acid)
Perchloric acid has only a conjugate base, and it is chlorate(VII) ion.
Perchloric Acid
Calcium phosphate is a neutral salt since it is formed from the reaction between a base (phosphate) and an acid (calcium). It does not have the characteristics of an acid or a base.
It is a base.
It is not a acid or base. It is a neutral compound.
Ammonium perhclorate is a salt. It is weakly acidic due to the presence of the ammonium ion.
Calcium sulfate is a salt because it is formed from the reaction between a base (calcium hydroxide) and an acid (sulfuric acid). It is a neutral compound with a 1:1 ratio of calcium ions (from the base) to sulfate ions (from the acid).
Potassium Perchlorate
Calcium itself is neutral.
Ca-acetate is a weak base, conjugated with a weak acid: H-acetate (i.e. acetic acid)
Perchloric acid has only a conjugate base, and it is chlorate(VII) ion.
Ca(ClO4)2 is calcium perchlorate.It is more often referenced as calcium perchlorate tetrahydrate = Ca(ClO4)2 . 4 (H2O)
No acid contains calcium carbonate. Calcium carbonate is its own compound that is a base, not an acid. However, the erosion and deposition of calcium carbonate in nature is heavily influenced by carbonic acid.
