Answer:
A very acidic pH level is 1, and a very basic pH level is 13.
I'm not sure I understand about your ratios, whether they are the choices or just numbers.
Explanation:
On the pH scale, the more you go to the left, the more acidic the solution is. Numbers below 7 are considered acidic, and the lowest number is the most acidic. The more you move to the right, the more basic or alkaline the solution is. Numbers above 7 are considered basic. So the higher the number of that side of the scale, the more basic stuff is. 7 is considered neutral.
