Acidic solutions?

Classify each of the following solutions as acidic, basic, or neutral based on the pH value.?

  • Well, I was working on my online homework for Chemistry and im given the pH value of 13.0, and I answered acidic since 13.0 is less than 7,but I do not know why I got it wrong. It was just 10^(-13) and it was less than 7. So, i do not know from there why acidic is not the answer. Can anybody help me out?? Thanks...Deeply appreciated:)

  • Answer:

    If you mean why a pH 13 is a base even though the number 10^(-13) is smaller than a pH of 7 (10^(-7)), is because the scale is based on a negative logarithm, so 10^(-13) is the amount of hydronium ions present, where as 10^(-7) has more hydronium ions, meaning its more acidic.

13.0 is more than seven, so it's alkaline Anything below 7 is acidic e.g 3 Anything above 7 is alkaline eg 12 7 Is neutral It's that simple just follow those rules :)

answer is basic. because ph=13 which is >7 ph<7, acidic ph>7, basic ph=7, neutral Hope that helps
