When a quality pH WebbpH scale is from 0 to 14. Acidic solutions such as Hydrochloric Acid, Acetic Acid etc have pH below 7 where as Bases such as Sodium Hydroxide have pH above 7. Usually, neutral solutions such as distilled water have pH of 7. pH is a numerical scale to represent acid, base or neutral solution on scale of 0 to 14. crypto-crashWebbA pH meter actually measures hydrogen-ion activity in water-based solutions. The liquid’s acidity or alkalinity is expressed as a pH unit. The pH scale ranges from 0 to 14, meaning a liquid with a pH below 7 is acidic and a pH above 7 is basic. A pH of 7 is considered neutral. durham police online reporting
