What is the color of a pure sulfuric acid?
It is transparent.
What is the color of sulphuric acid?
Sulfuric acid is colorless.
What is the color of phenoplhthalein if sulfuric acid is added?
The color is orange to red.
What happens if sulfuric acid is added in phenolphthalein?
Sulfuric acid is a strong mineral acid that can react with phenolphthalein, which is a pH indicator. In the presence of sulfuric acid, phenolphthalein can turn colorless due to the acidic conditions. This color change occurs because the sulfuric acid donates protons to the phenolphthalein molecule, changing its structure and causing it to lose its pink color.
What is the name of H2SO4 acid?
sulfuric acid or sulphuric acid
What is the color of sulfuric acid in qualitative test alkenes?
In qualitative tests for alkenes, sulfuric acid is typically colorless. When an alkene is added to sulfuric acid, it can lead to the formation of an alkyl hydrogen sulfate, which also remains colorless. The presence of color changes in the solution is not due to the sulfuric acid itself but rather to the products formed or the addition of indicators.
What is the color of lard with sulfuric acid?
When lard is mixed with sulfuric acid, it typically undergoes a chemical reaction that can darken its color. The lard may turn a yellowish to brown hue due to the breakdown of fats and the formation of various byproducts. The exact color can vary depending on the concentration of the sulfuric acid and the duration of exposure.
What color is car battery acid?
sulfuric acid is clear and is used in lead acid batteries for cars.
Why do you not test sulfates with sulfuric acid?
Sulfate ions (SO4^2-) do not react with sulfuric acid (H2SO4) because they are already in the sulfate form and are not further oxidized or reduced by sulfuric acid. The reaction of sulfuric acid with sulfates would not result in a color change or a precipitate formation, making it impractical as a test for sulfates.
What happens to glucose in the phenol sulfuric acid test?
In the phenol sulfuric acid test, glucose reacts with phenol and sulfuric acid to form a colored product. The color change is due to the formation of furfural, which reacts with the sulfuric acid to produce a colored compound. This color change is used to detect the presence of glucose in a sample.
What color does pH turn with sulfuric acid?
Sulfuric acid does not have a distinct color. When mixed with water, it forms a clear, colorless solution. pH papers can be used to test the acidity of the solution, which may change color depending on the pH level.
Sodium metavanadate in sulfuric acid gives a yellow color what happens when you add zinc granules to it and What is the role of the sulfuric acid in the first place?
When zinc granules are added to the solution of sodium metavanadate in sulfuric acid, the zinc reduces vanadate ions to vanadium(III) ions, which results in the formation of a blue color. Sulfuric acid is used to provide a suitable acidic environment for the reaction to take place and to stabilize the vanadium ions in solution.
