When electrolytes release more H+ (ions) than OH- (ions), the resulting solution is anacidwhile more OH- than H+, it is abase.
Acidityis measured based on the concentration ([ ]) of H+ and OH-. These are inversely proportionate: increased [H+]=decreased [OH-].
The measurement is a scale called the pH scale. It ranges from 0-14, with 7 being neutral (water). The scale:
Acids= high [H+], low [OH-],0-6= acidic Ex: HCl
Bases= low [H+], high [OH-], 8-14=basic or alkaline Ex: NaOH
Neutral= [H+]=[OH-], 7, water
Buffers: maintain the stability of acids-bases within the body. by taking up excess H+ or OH-.
