pH pH scale- measure of H+ ions (acidity); “power of hydrogen” #10.
PH Scientists use something called the pH scale to measure how acidic or basic a liquid is The scale looks at the concentration of positively charged hydrogen.
PH is the measurement of the concentration of H+ ions in a solution. (Or how acidic or basic a solution is.) 1. The pH scale has a range from 1 to 14.
