WebThe 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 are acidic while solutions with a primary question to answer is: "Is there evidence to indicate the mean pH of lakes in Florida is different than the neutral value of 7 ? Suppose the p-value =0.025. WebJan 30, 2024 · The pH of an aqueous solution is based on the pH scale which typically ranges from 0 to 14 in water (although as discussed below this is not an a formal rule). A pH of 7 is considered to be neutral. A pH of less than 7 is considered acidic. A pH of greater than 7 is then considered basic.
