Question

Which of the following base is used as antacid to neutralize stomach acidity?

• A. ${Mg\left(OH\right)}_2$
• B. $KOH$
• C. ${Ca\left(OH\right)}_2$
• D. $NaOH$

Answer 1

The correct option is A ${Mg\left(OH\right)}_2$

Magnesium hydroxide is also known as milk of magnesia and it is a common component of antacids and laxatives. It interferes with the absorption of folic acid and iron. It carries away much of the body's supply of potassium and neutralizes the stomach acid.
