in 1909 S.P.L Sorenson, a Danish biochemist devised a scale known as pH to represents the H + ion concentration of an aqueous solution. The pH value of any solution is a number that simply represents ...

Two types of acid-base titration stand out: alkalimetry and acidimetry. Each method provides a precise means to measure compounds based on their acid or basic content, depending on the type of the ...

The pH of the culture medium is a critical process parameter in cell culture bioprocesses. To successfully transfer processes between bioprocess systems and sites (i.e., in the course of process ...

Water molecules can break down into hydrogen ions and hydroxide ions. \(H_{2}O(l)\rightleftharpoons H^{+}(aq)+OH^{-}(aq)\) This is a reversible reaction. A small proportion of water molecules break up ...
