AP Chemistry Question of the Day --64

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.

AP Chemistry Question of the Day--52

Welcome back to my blog. The answer to question 51 is B. According to the Lowry-Brønsted definitions, acids are proton donors and bases are proton acceptors. If a species can both donate and accept a proton, it is called amphiprotic. Answers A and C can only be acids and answers B and D can only be bases.
Here is question 52 of the series:
52. An 11.1L sample of 0.25mol oxygen gas is converted to ozone. If all the oxygen is converted to ozone, what will the volume of ozone be?

I will post the answer in my next blog.
