ALiOH, NaOH, KOH, Mg(OH)2, Zn(OH)2, Ba(OH)2
BNH3, NaOH, KOH, Ca(OH)2, Sr(OH)2, Al(OH)3
CLiOH, NaOH, KOH, Ca(OH)2, Sr(OH)2, Ba(OH)2
DLiOH, NaOH, KOH, Ca(OH)2, Fe(OH)3, Ba(OH)2
Answer & Solution
Correct answer: C. LiOH, NaOH, KOH, Ca(OH)2, Sr(OH)2, Ba(OH)2
1. The six common strong bases are the hydroxides of lithium, sodium and potassium.
2. They are joined by the hydroxides of calcium, strontium and barium.
3. All six are soluble ionic hydroxides that dissociate completely in water.
4. Ammonia is a weak base, and the hydroxides of magnesium, zinc, aluminium and iron are not on the list.
