Science Experiments on pH Levels

Testing the pH level of a substance tells you if that substance is acidic basic or neutral The pH scale ranges from 1 to 14 7 is neutral lower numbers are acidic and higher numbers are basic Science experiments on pH levels help investigators determine the pH level of a given material and how that level might affect the environment

Experiments with Acids and Bases

Diluted acids and bases are less concentrated and less aggressive in their actions The acidic or basic degree of substances is measured in pH units The scale used spans from 0 to 14 Substances with pH lower than 7 are considered acids those with pH equal to 7 are considered neutral and those with pH higher than 7 are considered bases

Acids Bases the pH Scale

pH = −log [H+] The square brackets around the H + automatically mean concentration to a chemist What the equation means is just what we said before: for each 1-unit change in pH the hydrogen ion concentration changes ten-fold Pure water has a neutral pH of 7 pH values lower than 7 are acidic and pH values higher than 7 are alkaline
