WebJul 25, 2016 · pH is a measurement of the level of hydrogen ions in a solution, this sits on a globally established scale from 1-14. There is a range of ways used to test the pH of a … WebTest the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!
WebAn electronic pH meter is used for more precise measurements. A pH meter determines pH from the electrical potential between two electrodes in a solution. The potential varies with pH and activates an analog or digital meter calibrated to read pH directly to the nearest 0.01 or 0.001 unit. A pH meter is used when reliable knowledge or control ... WebStep 4: Compute the pH of the Solutions For the acids, use the formula pH = –log [H+]. (Because HCl has 1 H+ ion performula unit, [H+] equals the molarity.) For water, use what …
