Sulfuric acid will turn red on pH paper, indicating a very low pH level, typically around 0-1.
below pH 6.8above pH 8.26.8 yellow↔8.2 purple
Mixing bromothymol blue and sulfuric acid would not result in a colour change, as sulfuric acid is a strong acid and bromothymol blue is a pH indicator that changes colour based on the acidity or alkalinity of a solution.
We cannot tell the pH value of sulphuric acid without knowing the concentration of the sulphuric acid. As sulphuric acid is acid; so, its pH will be in the range of 1 to 6.9, depending upon its concentration.
Sulphuric Acid is colourless. When universal indicator (UI) is added, sulphuric acid remains colourless. The universal indicator turns 'RED'. Howver, because the UI is in solution with the sulphuric acid, the solution appears to be red.
Orange juice is acidic due to its citric acid content, which typically results in a pH below 7. When tested with pH paper, which changes color based on the acidity or alkalinity of a substance, orange juice would likely turn the pH paper to a color indicating acidity, such as red or orange. The exact color would depend on the pH range of the particular pH paper being used.

sulphuric acid is a stronger acid than carbonic acid. lower pH defines strength of acid.
Mixing bromothymol blue and sulfuric acid would not result in a colour change, as sulfuric acid is a strong acid and bromothymol blue is a pH indicator that changes colour based on the acidity or alkalinity of a solution.
Depending on the type of soil, the value of pH and the type of pH paper. For an acid soil the pH paper from Merck (art. 9565) this color will be probable green.

As orange contains acidic substances, a piece of pH paper would indicate a colour which is in the acid range and the strict colour may differ according to the fruit too.
Orange juice is acidic due to its citric acid content, which typically results in a pH below 7. When tested with pH paper, which changes color based on the acidity or alkalinity of a substance, orange juice would likely turn the pH paper to a color indicating acidity, such as red or orange. The exact color would depend on the pH range of the particular pH paper being used.
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.
