## PH scale,

### Definition of PH scale:

1. A measure of the acidity of a water soluble substance (pH value means hydrogen potential). The pH value is a number between 1 and 14, with 7 midpoints (neutral points). A value below 7 indicates that the acidity increases as the number decreases, with 1 having the highest acidity. The value of which is greater than 7 which indicates increasing algebra as the number increases, 14 is the most basic. However, it is not a linear scale like the scale of centimeters or inches (where the two adjacent values ​​have the same difference). This is a logical scale where two neighboring values ​​increase or decrease by a factor of 10. For example, pH 3 is ten times more acidic than pH 4 and pH 4 is 100 times more acidic. PH 5 In addition, pH 9 is 10 to 10 times more alkaline than pH 8 and 100 times more alkaline than pH 7. Invented in 1909 by the Danish biochemist SP Sorensen (1869-1939).
