Universal Indicator pH colours Notice that the colours for acids and alkalis are different when using a universal indicator. Universal Indicator pH Scale Results When using the red cabbage indicator, the colour of the liquid will change from purple to red if it is an acid and from purple to g...
some moderately while others show no reaction. To determine the strength of acids and bases quantitatively, we use a universal indicator which shows different colours at different concentrations ofhydrogen ionsin solution. Generally, the value of pH of acids and bases are used to quantitatively deter...
So, the pH scale is developed to measure the hydrogen ion concentration. Its values range from 0 to 14, which are known as pH values. So, we can say that the pH value is a number that indicates the acidic and basic nature of a solution. Limitations of pH scale There are somelimitatio...
we analysed median optical sections through the follicles. Representative grey-scale images were transferred into pseudocolour images using ImageJ Fire-LUT (NIH, USA). For immunostaining as well as fluorescent inhibitors, brighter colours represent higher concentrations of the respective membrane...
