WebMar 2, 2024 · pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 … WebThe pH scale ranges from 0 to 14, with a pH of 7 indicating neutrality, values less than 7 indicating acidity, and values greater than 7 indicating basicity. The pH scale is based on the hydrogen ion concentration, with each pH value representing a tenfold difference in hydrogen ion concentration. p [H] [ edit]

WebIf you want an accurate measurement you will typically use a device called a pH meter§. There are also chemicals called pH indicators that can be used. These chemicals are often bound onto small strips called pH paper than change color to give you an estimate of the pH. WebThe pH scale was developed by chemist Soren Sorenson in 1909 as a more convenient way to quickly compare the acidity of different solutions. The pH of a solution is the negative logarithm of its hydronium ion concentration. For example, a solution with 1 × 10 −5 M hydronium concentration has a pH of 5. The greater the hydronium ion ... detox retreats in thailand
