Which of the following salts is formed from a strong acid and a strong base?a) Sodium sulfate (Na2SO4)b) Ammonium chloride (NH4Cl)c) Calcium carbonate (CaCO3)d) Potassium nitrate (KNO3)
Question
Which of the following salts is formed from a strong acid and a strong base?a) Sodium sulfate (Na2SO4)b) Ammonium chloride (NH4Cl)c) Calcium carbonate (CaCO3)d) Potassium nitrate (KNO3)
Solution
The salt formed from a strong acid and a strong base is d) Potassium nitrate (KNO3).
Here's the step-by-step explanation:
-
A strong acid and a strong base completely ionize in solution, meaning they break down into their ions completely.
-
A strong acid could be nitric acid (HNO3), and a strong base could be potassium hydroxide (KOH).
-
When these two substances react, they neutralize each other to form water (H2O) and a salt.
-
The salt formed in this case would be potassium nitrate (KNO3), which is the combination of the potassium ions (K+) from the strong base and the nitrate ions (NO3-) from the strong acid.
-
Therefore, the answer is d) Potassium nitrate (KNO3).
