WebAboutTranscript. The 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. WebMilk is considered a base because of its pH level. pH is a measure of the acidity or alkalinity of a solution, and every solution has a pH value between 0 to 14. A pH value …
WebThe pH scale is considered a logarithmic scale corresponding to the concentration of protons (H+ ions) in aqueous solutions. So, pH is the negative log of [H+] and can be calculated using the following formula: = - log 10 H +. Some textbooks use [H3O+] to refer to the concentration of protons instead of [H + ].
