Answer

Brief Explanations:

Milk of magnesia is (\ce{Mg(OH){2}}). It can react with stomach acid ((\ce{HCl})) according to the reaction (\ce{Mg(OH){2}+ 2HCl=MgCl_{2}+2H_{2}O}). Bases react with acids to form salt and water. An acid would not neutralize stomach acid. An indicator is used to show the pH - change (like color - change in the presence of acid or base). A colloid is a type of mixture (like a dispersion of particles in a medium) and has no role in neutralizing acid.
