A. $N{{a}_{2}}C{{O}_{3}}$
B. $CaC{{O}_{3}}$
C. $ZnC{{O}_{3}}$
D. $A{{l}_{2}}{{\left( C{{O}_{3}} \right)}_{3}}$

Answer 1

Hint: An antacid or acid neutralizer is a kind of substance which kills stomach acidity and is utilized to diminish indigestion, heartburn or an annoyed stomach. Acid neutralizers contain soluble particles that artificially kill stomach gastric corrosive, lessening harm and soothing torment.

Complete step by step answer:
Instances of acid neutralizers areSodium hydrogen carbonate, Magnesium hydroxide, Aluminium carbonate, Aluminium hydroxide. Sodium carbonate known as washing soft drink is very antacid in nature and has a frightful foamy taste. It isn't truly tasteful and could consume the throat. Bicarbonate is a lot gentler and not as unequivocally basic, and therefore more satisfactory. Subsequently, it won't go about as Antacid. Because of their essential substance nature, stomach settling agents can kill gastric corrosive; however they offer just a brief increment in the intragastric $pH$ Stomach settling agent arrangements are commonly made out of aluminum and magnesium hydroxides. Some of them consolidate the continued impact.
The reason is has smaller ionic size as compared to the other elements of that group due to its half-filled stable valence shell configuration Now hydration energy is inversely proportional to the square of the cationic size and lattice energy is directly proportional to the charges of the ions and inversely proportional to the radius of the ion. From the above relations, we can derive that lattice energy is more than hydration energy in this case. So, $A{{l}_{2}}{{\left( C{{O}_{3}} \right)}_{3}}$ remains insoluble in water.

So, the correct answer is Option D.

Note: This drug is utilized to treat the side effect of an excessive amount of stomach corrosive, for example, stomach upset, acid reflux, and corrosive heartburn. It is additionally used to calm indications of additional gas, for example, burping, swelling, and sentiments of weight/distress in the stomach/gut.
