  1. acid

  2. antacid

  3. alkali

  4. rock salt
Reveal answer Fill a bubble to check yourself
B,C Correct answer
Explanation

Milk of magnesia is $Mg(OH) _2$, it is an alkali.

Antacid is those compounds which completely neutralizes an acid.
For example: $\underbrace{Mg(OH) _2} _{Base}+\underbrace{H _2SO _4} _{Acid}\longrightarrow  \underbrace{MgSO _4} _{Neutral\ salt}+H _2O$
Thus, milk of magnesia is also an antacid.

  1. $Ca(OH) _2$
  2. $Al(OH) _3$
  3. $FeOH$
  4. $KOH$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Aqueous potassium hydroxide is employed as the electrolyte in alkaline batteries based on nickel-cadmium, nickel-hydrogen, and manganese dioxide-zinc. Potassium hydroxide is preferred over sodium hydroxide because its solutions are more conductive.
