Are Florida Lakes Acidic or Alkaline? The pH of a liquid is a measure of its acidity or alkalinity. Pure water has a pH of 7, which is neutral. Solutions with a pH less than 7 am acidic while solutions with a pH greater than 7 are basic, or alkaline. The dataset Florida Lakes gives information, including pH values for a sample of lakes in Florida. Computer output of descriptive statistics for the pH variable is shown: Descriptive Statistics: pH Variable N N° Mean pH SE Mean 6.591 0.177 1.288 53 0 Click here for the dataset associated with this question. n= Enter the exact answers.
