Coffee has a pH of five. Is it acidic, basic, or
neutral?
To answer this question, let’s
review what we know about pH in general. pH is a measure of how acidic or basic
something is, with neutral being right in the middle. pH ranges from zero to 14. If something has a pH of zero, it’s
very acidic while something with a pH of 14 is very basic. A pH of seven, which is right in
the middle, means that something is neutral, i.e., something that’s neither acidic
nor basic.
pH values less than seven are
considered acidic while pH values above seven are considered basic. So now let’s take another look at
our question. We’re told that coffee has a pH of
five. On our scale, we can see that pH
five is just below pH seven and is in the acidic range.
This tells us that coffee with a pH
of five is acidic. So this is our answer.
