Hydrochloric Acid is known to be a very strong acid. A 0.01 molar solution of HCl has a pH of 2 ( -log(0.01) ) which on the pH scale is very acidic (under 7 is acidic, 7 is neutral, over 7 is basic). On a universal indicator test, HCl would come out as red. A basic solution would be a more blue-green, or green depending on the concentration.
This is a color chart for a universal indicator test:

Hydrochloric acid at pH 1 would turn universal indicator red, indicating a strongly acidic solution.
Universal indicator changes color to red in the presence of hydrochloric acid in the stomach, indicating a low pH.
Hydrochloric acid will typically turn universal indicator paper red, indicating a low pH or acidity. Universal indicator paper changes color based on the pH of the solution it comes into contact with, with red indicating a strong acid.
No, universal indicator does not turn red when diluted in water. Instead, it changes color depending on the pH of the solution, ranging from red (acidic) to green (neutral) to purple (basic).
When hydrochloric acid reacts with iron, it forms iron(III) chloride, which appears red in color. This happens because of the oxidation state change in the iron ions during the reaction, leading to the red coloration.

A green colour will appear due to the reaction of hydrochloric acid and sodium hydroxide. The universal indicator changes color in response to the pH level of the solution, and green indicates a neutral pH level.
The color of a universal indicator in a basic solution is usually purple or blue.
Universal indicator changes color in different pH ranges. In the case of ethanol, which is pH-neutral, universal indicator would likely show a green color.
Green is the color that universal indicator turns to when it is neutral.
When universal indicator is put in water soluion of alkalis (base) it indicates significant blue colour.
Hydrochloric acid itself is a colorless solution. However, it can turn red when it is in contact with certain chemicals or impurities that might be present in the environment. The red color typically indicates a reaction or contamination rather than a natural property of hydrochloric acid.
since water is pretty neutral, the water does not change color but the universal indicator does. The universal indicator changes color as per the quantity of deionized water... But it changes to straw color or pale yellow in 50mL of deionized water.
