The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
Methyl red is a pH indicator used to identify pH values between 4.4 and 6.2. At low pH (4.4 and lower) the indicator solution is red. At high pH (6.2 and above) the color is yellow. Between pH 4.4 and 6.2, the indicator solution is orange. Bromocresol greenis a pH indicator used t...
CO2 will readily dissolve in distilled water (or any water, but more so in distilled because it's 'empty' water). This can be proven. Add phenolphthalein indicator to distilled water. Let's presume the pH was 7 or just slightly below. the indicator should be a slight pink color. If yo...
What is the purpose of using a strong acid like sulphuric acid in fluorescence spectroscopy? What do we mean by the equivalence point in a titration? Why does chromatography work? The color change of the phenolphthalein, the indicator, at an end point can be explained in terms of which of ...
What is a qualitive test that can be done based on solubility that would differentiate a pure acidic organic compound from a neutral organic compound. How would the test be done ? What results wou The color change of the bromothymol blue with water is caused by carbon dioxide from ...
Why is bromothymol blue a good indicator with which to test all solutions first? What are some causes of a high percent error when titrating Ca(OH)2 with HCl and phenolphthalein indicator? The color change of the phenolphthalein, the indicator, at an end point can be explained in terms of...
