Test question: "Water has pH of 7. Which solution has a [H+] concen.."
1.
2. First of all, increasing [H+] concentration will give something more acidic. Since every jump between pH numbers is a 10 fold difference, I thought that to make a 100 fold difference, you would have to do 10x10, which would cause the pH number to go down by two steps.
That's why I chose A (bananas with a pH of 5).
The actual answer is B (milk with a pH of 6).
How does pH decrease by only 1 step?
Would you please explain this to me?
Thank you so much! :)
