What colour does red litmus paper turn when dipped in sulfuric acid?
Red litmus paper will turn blue when dipped in sulfuric acid because sulfuric acid is a strong acid and will cause the litmus paper to undergo a color change from red (indicating acidic pH) to blue (indicating a basic pH).
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 colour would the red petal indicator be in sulphuric acid?
The red petal indicator would turn blue in sulfuric acid. This color change occurs due to the strong acidity of sulfuric acid causing a shift in the pH level, resulting in the red petal indicator changing color.
What is the colour of sulphuric acid on pH paper?
Sulfuric acid will turn red on pH paper, indicating a very low pH level, typically around 0-1.
What colour should sulfuric acid be after universal indicator is added?
Sulfuric acid is a strong acid and will turn universal indicator red when added, indicating a pH of around 0-1.
What colour does red litmus paper turn when dipped in sulfuric acid?
Red litmus paper will turn blue when dipped in sulfuric acid because sulfuric acid is a strong acid and will cause the litmus paper to undergo a color change from red (indicating acidic pH) to blue (indicating a basic pH).

Sulfuric acid is a strong acid and will turn universal indicator red when added, indicating a pH of around 0-1.
What is the pH level of 1 molar of sulfuric acid?
The pH level of 1 molar sulfuric acid is around 0.3. This makes it a strong acid.
What happens when you add universal indicator to sulfuric acid?
When universal indicator is added to sulfuric acid, the solution will turn red as sulfuric acid is a strong acid. It indicates a highly acidic pH level in the solution.
What you pH value when 100 percent sulfuric acid?
100% sulfuric acid rapidly decomposes until it reaches a concentration of 98%. This concentration is usually referred to as concentrated sulfuric acid. The pH value of 98% sulfuric acid is approximately -1.5 For comparison, sulfuric acid of this concentration has about 300 times as many active hydrogen ions as stomach acid (approximate pH 1).
What is the pH of sulfuric?
The pH of sulfuric acid depends on its concentration. For a 1M solution, the pH would be around 0.3, indicating it is highly acidic.
What is pH of h2so4?
The pH of a 0.1 M solution of sulfuric acid (H2SO4) is around 1. Note that the pH of sulfuric acid solutions will vary depending on concentration.
Why does a 1 molar solution of sulfuric acid have lower pH than 1 molar solution of acetic acid?
Sulfuric acid is a strong acid, meaning it completely ionizes in water to release more protons (H+) compared to acetic acid, which is a weak acid and only partially ionizes. This higher concentration of protons in the solution of sulfuric acid results in a lower pH compared to acetic acid at the same concentration.
What is the ph number for sulphric acid?
The pH value of any acidic solution depends on the strength of the acid in the particular solution. In this instance, a dilute sulfuric acid solution shows a higher value of pH whereas the concentrated acid shows a very low value.
