[Ger. Potenz, ability + H, symbol for hydrogen] In chemistry, a measure from the hydrogen ion concentration of a solution. The degree of acidity or pH value alkalinity of a substance is expressed within a website pH value. A solution that is certainly neither acid nor alkaline provides a pH of seven. Rising acidity is expressed for a range fewer than 7, and growing alkalinity as being a quantity increased than 7. Highest acidity is pH 0 and highest alkalinity is pH 14. Because the pH scale is logarithmic, There's a 10-fold difference between Every device.
