The pH scale runs from pH 0 to pH 14. pH Measure of acidity (0-6) or alkalinity (8-14).
|< 1||1,5 - 4||4 - 6||6,8 - 8,5||8,5 - 11||11 -13||> 13|
|strong acid||acid||weakly acidic||neutral||weakly alkaline||alkaline||strongly alkaline|
Chemical substances, compounds, mixtures that have an excess of H+ (Hydrogen) ions. When measured on a pH meter give a reading of 0 to 6. The lower the number, the more H+ ions and the stronger the acid. Organic acids (fruit) typically have a pH of 4 - 6.
Pure water is pH neutral.
It has one H+ ion (Hydrogen) and one OH- ion (Hydroxide) = H2O.
Neutral chemical substances, compounds, mixtures when the OH- and H+ ions are in balance. Neutral substances have pH of 7.
Chemical substances, compounds, mixtures that have an excess of hydroxide ions (OH-). When measured on a pH meter give a reading of 8 to 14. The higher the number, the higher the concentration of the ions.
