Hey

● pH scale is used to measure the concentration of hydrogen

● It has values from 0 to 14

● Values less than 7 are acids and greater than 7 are bases

● Values equal to 7 are neutral solutions

● When the pH value increases the concentration of hydrogen ion decreases

● The word pH was derived from German which means potenz (power)
