Color has historically seen limited use in metallography, mainly due to the cost of film and prints and the difficulty and cost of reproducing images in publications. However, with the growth of digital imaging, capturing color images is much simpler and cheaper. Also, printing images in color ...
4、, methyl orange reagent, Br2 (CCl4) is orange-red.(2) chemical changes: methyl orange in an acidic solution (3.1 pH 4.4) is orange and methyl red is orange in acid solution (4.4 pH 4.4).The concentrated nitric acid turns yellow due to the decomposition of nitrogen dioxide4. Green ...
What color did the bromothymol blue indicator turn when it was added to the test tube containing citric acid? a. Colorless b. Yellow c. Blue d. Red pH Indicators: The pH scale is used to determine how acidic or basic a sub...
The blue color of dextran blue solution is due to the well-known, blue complex formed between starches and iodine. If you only had the absorption spectrum of this solution, explain why its color could be predicted, based on the spectrum alone. In what par ...
Hello everyone. Firstly I apologize if this is somewhat an odd post, for I am not a chemist or enrolled to study chemistry. What I am is an artist. I ended up in your graces due to wanting to learn more about rust and the process of rusting - and in particular, if there was any...
Aqueous KMnO4, a purple solution, requires a wavelength of approximately 565 nm. Explain why different wavelengths of light are selected to measure the absorbance of KMnO4 and CuSO4 s A yellow dye, FD&C yellow 3, is used in some...
Answer to: When a good indicator has been chosen, the pH at which the solution changes color is very close to the... point of the...
Is "a color of solution becoming less intense due to dilution" maybe evidence of chemical reaction or not? 1) It has been noted that the basic solutions containing Bromothymol blue, after sitting in open air, undergo a color c...
Flame test is a qualitative test used to identify the presence of specific metal ions. The gas or vapor particles of the metal ion may be excited by the heat energy resulting in the promotion to a higher energy level. When it goes back to the ground...
