http://chemistry.elmhurst.edu/vchembook/184ph.html WebMar 5, 2024 · A proton is a positively charged particle (and is the nucleus of the hydrogen atom). On a pH scale, acids all fall below 7. The opposite of an acid is a base. Chemists describe these molecules as being alkaline (AL-kuh-lin). Brønsted-Lowry bases are good at stealing protons and will gladly take them from acids. One example of a base is ammonia.

WebThe pH scale measures how acidic or basic a substance is. The scale ranges from 0 to 14 and is based on the concentration of hydrogen ions in a solution. Pure or distilled water is neutral—it has an equal number of hydrogen and hydroxide ions—so it falls at the middle of the scale with a pH of 7. WebNov 29, 2024 · The pH scale ranges from 0 to 14, with 0 indicating extremely acidic and 14 indicating extremely alkaline. If a pH value of 7 is found in any solution, it indicates that the solution is neutral in nature. Values less than 7 suggest an acidic solution, whereas values more than 7 indicate an alkaline solution. WebThis acid-base chart includes the K a value for reference along with the chemical's formula and the acid’s conjugate base.
