indicator solution मीनिंग इन हिंदी

उदाहरण वाक्य

1. HCl has a higher conductivity that the " indicator solution"
2. Onset of rusting can also be detected in laboratory with the use of ferroxyl indicator solution.
3. For instance, suppose an indicator solution changes color in the presence of a metal ion.
4. It could be used as a qualitative test : does the indicator solution change color when a drop of sample is added?
5. One method of testing a structure for carbonatation is to drill a fresh hole in the surface and then treat the cut surface with phenolphthalein indicator solution.
6. It could also be used as a quantitative test, by studying the color of the indicator solution with different concentrations of the metal ion . ( This would probably be done using ultraviolet-visible spectroscopy .)
7. Potassium ferricyanide is also one of two compounds present in ferroxyl indicator solution ( along with phenolphthalein ) which turns blue ( Prussian blue ) in the presence of Fe 2 + ions, and which can therefore be used to detect metal oxidation that will lead to rust.
8. A precaution that should be observed is to add the starch indicator solution only near the end point ( the end point is near when fading of the yellowish iodine colour occurs ) because at high iodine concentration starch is decomposed to products whose indicator properties are not entirely reversible.
