How many milliliters of 3.0 M H2SO4 are required to neutralize 30.0 ml of 4.0 M NaOH?
A. 15
B. 20
C. 25
D. 30
E. 40
Explanation:
Correct Answer: B
Without the need to express a full chemical equation, it is obvious that only 0.5 mole of H2SO4 is required to neutralize every mole of NaOH.
Using simple proportional relation, amount of H2SO4 required will therefore be:
HOW IS IT OBVIOUS THAT ONLY 0.5 MOLE OF H2SO4 IS REQUIRED TO NEUTRALIZE EVERY MOLE OF NaOH????????
