of Household Substances                                                The pH of a substance lets us know if it is an acid or a base. The pH is based on the concentration of hydrogen ions. The more hydrogen ions in a solution, the more acidic the solution is. Materials: Your lab kit and 10 household liquids or solids (liquids are easier to use) Safety: Wash hands before and after this lab. Do not work near food or drink. Concentration formula: Concentration = 10 -pH Example: For pH = 1 , Concentration = 10 - 1 written in exponent form = 0.1 in standard form Part I. Complete the pH chart: pH Concentration in exponent form Concentration in standard form 1 10 -1 0.1 2 10 -2 0.01 3 10 -3 0.001 4 10 -4 0.0001 5 10 -5 0.00001 6 10 -6 0.000001 7 10 -7 0.0000001 8 10 -8 0.00000001 9 10 -9 0.000000001 10 10 -10 0.0000000001 11 10 -11 0.00000000001 12 10 -12 0.000000000001 13 10 -13 0.0000000000001 14 10 -14 0.00000000000001 pH is greater than 7 Neutral – pH is equal to 7
