WebpH Scale and Acid/Base Overview. The pH scale is a measure of how acidic or basic a solution of water is. Acidity refers to having a high concentration of hydrogen ions (sometimes also called or protons), while basicity (or alkalinity) refers to having a low concentration of hydrogen ions. These concentrations of protons are usually very small ... marescotti morteWebThe pH scale is a convenient way to represent the acidity or basicity of a solution. We can calculate the pH of a solution by taking the negative logarithm of the hydronium ion concentration, or pH = -log [H₃O⁺]. At 25°C, a solution with pH < 7 is acidic, a solution with pH > 7 is basic, and a solution with pH = 7 is neutral. Created by Jay. marescotti moglieWebMar 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. marescotti tumoreWebSample Learning Goals. Determine if a solution is acidic, basic or neutral. Place acids or bases in order of relative acidity or basicity.
