Question

The antacid property of Aluminium phosphate is due to. A.the primary phosphate ion. B.the secondary phosphate ion. C.the tertiary phosphate ion. D.the quaternary ion​

Answer 1

hey mate this might help

quaternary (4º) ammonium ion is an ammonium ion that has the following general structural formula. R1, R2, R3, and R4 could be alkyl groups, aryl groups, or any combination thereof. eg: see also quaternary ammonium salt, primary ammonium ion, secondary ammonium ion, tertiary ammonium ion

Answer 2

Answer:

The antacid property of Aluminium phosphate is due to the presence of tertiary phosphate ion.

Explanation:

Phosphate is a phosphate anion which is a polyanion that consists of phosphorus and oxygen. The phosphate polyanion has the molecular formula PO₄³⁻ having an electrical charge of -3. The use of aluminum phosphate compound is as an antacid because it neutralizes the stomach acid by aluminum phosphate which then forms aluminum chloride. For a phosphate compound or salt, there should be a cation with a positive charge and the same value as that of an anion. Here, aluminium is the cation as it has the property to lose three of its electrons in the outermost shell to get a complete octet configuration.

Hence, Aluminium phosphate shows the antacid property due to the presence of tertiary phosphate ion. Hence, the correct option is (c) the tertiary phosphate ion.
