When is an aqueous solution basic? What pH?

2 Answers

Answer:

It is basic at #25^@ "C"# and #"1 atm"#, when pH is greater than 7.

Explanation:

For any aqueous solution at #25^@ "C"# and #"1 atm"#:

  • #"pH" = 7 rightarrow "neutral"#
  • #"pH" < 7 rightarrow "acidic"#
  • #"pH" > 7 rightarrow "basic"#

We may note that pH can take any value (even negative values or equal to zero).

P.S. I do not have too much time, but I strongly recommend you to take a look at the definition of pH as the logarithm of #"H"^{+}"# concentration, i.e. #"pH" = -log["H"^(+)]#.

Answer:

Basic

Explanation:

The higher the pH number is, the more alkaline (or basic) it gets.
Neutral is 7 so anything higher than 7 is alkaline and anything lower than 7 is acidic.
