WebbIntracellular pH is generally between ~6.8 and 7.4 in the cytosol and ~4.5 and 6.0 in the cell’s acidic organelles. Unlike intracellular free Ca 2+ concentrations, which can rapidly change by perhaps 100-fold, pH inside a cell varies by only fractions of a pH unit, and such changes may occur quite slowly. We offer a range of indicators for ... WebbClass practical. Phenolphthalein is an indicator that is pink in alkaline solutions of about pH10. When the pH drops below pH 8.3 phenolphthalein goes colourless. Here, an alkaline solution of milk, lipase and phenolphthalein will change from pink to colourless as the fat in milk is broken down to form fatty acids (and glycerol) thus reducing the pH to below 8.3.
