SOLUTION

pH, Acids, and Bases

The pH of a solution indicates its acidity or basicity. pH measures the hydrogen ion concentration in a given solution. The concentration of hydrogen ions dissociating from pure water is .The pH log  is equal to a pH of 7.0, which yields a neutral pH. Non-neutral pH results from the dissolving of acids or bases within pure water. Continuing with the use of the logarithm, high concentrations of hydrogen ions will result in a low pH number, and lower concentrations of hydrogen ions will result in a high pH number.…..Please click the icon below to access entire solution at $10
