Test question: "Respiring cells release CO2 into the bloodstream..."
1.
2. For this question, I was thinking about the nature of CO2.
It's not an acid or base, so how could it drop or raise the pH level?!
So I put that the pH level won't change (B), but the real answer is C (it will decrease slightly).
How is this? How can a neutral substance make the blood more acidic?
Or is it really NOT neutral...? Hm.
Would you please explain why the pH value gets lowered?
Thank you so much! :)
