Introduction's ph
WebAnd, since pH = –log[H+] and pK a = –log K a, then, pH = pK. a + log([A –]/[HA]) This last equation is the Henderson-Hasselbalch equation. It reveals the relationship of pH and pK. a. Remember that pH is a measure of the acidity of a solution while pKa is a measure of the affinity of a molecule for its proton. The former can be altered Webd) use of the expression for pH as: pH = –log[H⁺]; [H⁺] = 10⁻ᵖᴴ; e) use of the expression for the ionic product of water, Kw; f) calculations of pH, or related quantities, for: strong …

WebpH = −log ([H +]) The formula for pH is shown above. pH is defined as the negative log base 10 of the hydronium concentration. The pH is a logarithmic measure of the concentration of hydrogen ions in a solution. Because pH is on a log scale that means that increasing the pH by 1 corresponds to multiplying the concentration of H + ions by 10 WebAn Introduction to pH, The concept of pH was first introduced by the Danish chemist Søren Peder Lauritz Sørensen at the Carlsberg Laboratory in 1909.
