I have not written here for a long time. AP season is coming soon in a couple of months. I will resume my series and hopefully it is helpful to anyone who come across to visit this site. Instead of posting a question and answer it the next day, I am going to post the question and answer at the same time.
Question 64: Which one of the following cidic solutions requires the most 0.1000M NaOH aqueous solution to neutralize completely:
A. 0.1000M HCl 25ml
B. 0.1000M HF 25ml
C. 0.05000M H2SO4 25ml
D. 0.05000M H2CO3 25ml
E. They are all the same
The answer to this question is E. When an acid and a base react, whenever there is a strong acid or base involved, the reaction will go to completion. The amount of base required will be totally determined by the mole number of the protons in the acid. It does not matter the acid is strong or weak, monoprtotic or diprotic. It is the number of moles of H+ that is in the acid that determines how much base will be needed to completely neutralize.
Hope this helps with your understanding on acid and base and thank you for visiting my blog.
