Webb17 juni 2024 · Based on below equations, when you use H2PO4- salts (e.g., NaH2PO4) you will decrease your solution pH. However, when you use PO4- salts (e.g., Na3PO4) you will increase your solution pH,... WebbIt is a measurement of the hydrogen ion concentration. pH is defined as the negative logarithm (base 10) of hydrogen ion concentration. If the hydrogen ion concentration is very high, the pH value is very low. This is determined using a scale ranging from 0-14 called the pH scale. It was introduced by a Danish chemist Soren Peder Lauritz Sorensen.
