Understanding pH can help you predict the properties of a solution, including the reactions it will complete. A pH of 7 is considered … acm homey WebThe pH scale actually is based on another scale. We usually keep track of the concentration of solutes in moles per liter (M). The pH is minus the log (base 10) of the H + concentration in moles per liter. Since at room temperature in pure water, that concentration is very close to 10-7 M, pH 7 is neutral. Mike W. (published on 09/17/2009) WebA solution with a pH less than 7 is considered acidic, and a solution with a pH greater than 7 is considered basic, or alkaline. Strong acids have a higher concentration of hydrogen ions, and they are assigned values closer to 0. Conversely, strong bases have higher concentrations of hydroxide ions, and they are assigned values closer to 14. ac mhr 25080 si WebThe 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.
