WebFor example, if we have a solution with [\text {H}^+]=1 \times 10^ {-5}\text { M} [H+] = 1×10−5 M, then we can calculate the \text {pH} pH using Eq. 1a: \text {pH}=-\log (1 \times 10^ {-5})=5.0 pH = −log(1 × 10−5) = 5.0 Given the \text {pH} pH of a solution, we can also find … WebJun 28, 2024 · The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value.
WebJan 16, 2024 · The pH is defined by the following formula, where [H +] is the concentration of hydrogen ions in the solution. pH = − log([H +]) = log( 1 [H +]) The equivalence of Equations 6.5.1 and 6.5.2 is one of the logarithm properties we will examine in this section.
