... Acidity: Degree of being acidic. It depends on the concentration of hydrogen ions in a solution. 2. I will emphasize the difference between strong acid and more acidic. Strong acids are acids (bases) that have a higher degree of ionization. Thus, even small amount of molecules can produce large numb ...
