Question

14. A solution with a pH of 13 is a ____. (1 point)
weak acid
strong acid
weak base
strong base
Im in bio and im very confused about this question! PLEASE HELP!

Answer 1

It would be a strong base, as 13 is higher on the scale of pH for high alkalinity.

Answer 2

Let me explain the pH scale for you.

The pH scale goes from 0 to 14.

0 is very ACIDIC.

7 is NEUTRAL (Like the water that we would drink).

14 is very BASIC.

~~~~~~~~~~

13 is very high up on the pH scale.
It's very close to 14.

And like TrashMan914 says, that means it's a strong base. It's very BASIC.

You see?

Answer 3

Um..Ok :) Thanks! :)

Answer 4

Yeah you're welcome.

I mean, do you think you understand everything? I don't know if my wording was very clear.

Answer 5

This page explains the pH scale, and gives a chart from pH of 0 - 14 including examples of the substances you'd find at each level.

Answer 6

Im not very good at understanding things...so its not u its me. But thanks anyway :)

Answer 7

Biology and Chemistry were some of my best subjects, so, if you've got any more questions, just mention me on your post by typing @TrashMan914 on it.
