WebbThe pH scale is a measure of how acidic or basic a solution is and it ranges from 0 to 14. As you can see in the image above, acidic solutions have a pH of less than 7, whereas bases have a pH higher than 7. Solutions with a pH of 7, such as water (H 2 O), are considered neutral. WebbpH = −log ([H +]) The formula for pH is shown above. pH is defined as the negative log base 10 of the hydronium concentration. The pH is a logarithmic measure of the concentration of hydrogen ions in a solution.

WebbThe 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. WebbThus, pH may be defined as a measure of free acidity. More precisely, pH is defined as the negative log of the hydrogen ion concentration. The range of pH extends from zero to 14. A pH value of 7 is neutral, because pure water has a pH value of exactly 7. Values lower than 7 are acidic; values greater than 7 are basic or alkaline.

WebbReading the pH scale. The pH scale is used to rank solutions in terms of how acidic or how basic they are. It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution. WebbThe pH of a substance is a measure of how acidic or basic the substance is. Measured on a scale from 0 to 14, pH is based on the concentration of hydrogen ions in a solution. In pure water, which is neutral (neither acidic nor basic), the concentration of hydrogen ions corresponds to a pH of 7.0. This marks the midpoint of the pH scale.
