14 with 7 being neutral pHs of less than 7 indicate acidity whereas a pH of greater than 7 indicates a base pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water The pH scale The pH scale is used to rank solutions in terms of acidity or basicity alkalinity Since the scale is based on pH values it is logarithmic meaning that a change of 1 pH unit corresponds to a ten-fold change in H ion concentration The pH scale is often said to range from 0 to 14 and most solutions do fall within this range pH Scale a scale used to define the levels of hydrogen H or hydroxide OH ions in a solution Ranges from 0 acidic to 14 basicalkaline with 7 being neutral Label the pH scale below indicating the acidity of a solution in the given regions Indicate the color of phenolphthalein within the pH ranges shown below pH basic 2 3 4 approximately neutral weakly basic O colorless pH 83 weakly acidic faintly pink O bright fuchsia acidic 6 O colorless 9- 83 pH 1 faintly O bright fuchsia O colorless O bright fuchsia 12- pH10O faintly pink The pH scale ranges from 0 to 14 The pH of a solution is a measure of its acidity or alkalinity base You have probably used litmus paper paper that has been treated with a natural water-soluble dye so it can be used as a pH indicator to test how much acid or base alkalinity exists in a solution Increases Acidity 1 Adding 1M H- to a solution 2 Decreasing pH Decreases Acidity 1 Adding 1M -OH to a solution 2 Removing H-3 Adding base 4 Removing acid 5 Adding 1M H- to a solution while simultaneously adding 2M -OH The pH Scale Acidic Neutral and Basic The pH scale describes the acidity of the solution acidic neutral or basic A solution with a pH less than 7 is an acid exactly 7 is a neutral solution and above 7 is a base Bases have less hydrogen ions but more hydroxide ions represented by the pOH or “potential of hydroxide ions” Table 1 LAbel the pH scale below indicating the acidity of a solution in the given regions Indicate the color of phenoiphthalein within the pH ranges shown belovw pH O colorless ° pH 83 faintly pink bright fuchsia O neutra O colorless 983pH 10faintly pink 10 -

log H + or pH = - log H 3 O + 3 The pH scale is the range of pH values from 0 to 14 The pH scale measures how acidic or basic a substance is The pH scale ranges from 0 to 14 A pH of 7 is neutral A pH less than 7 is acidic A pH greater than 7 is basic The pH scale is logarithmic and as a result each whole pH value below 7 is ten times more acidic than the next higher value ‪pH Scale‬ -
