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.

What else can I help you with?
What color would hydrochloric acid pH 1 turn universal indicator?
Hydrochloric acid at pH 1 would turn universal indicator red, indicating a strongly acidic solution.
What is the colour with universal indicator hydrochloride acid in stomach?
Universal indicator changes color to red in the presence of hydrochloric acid in the stomach, indicating a low pH.
What effect does hydrochloric acid have on universal indicator paper?
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.
Does it turn universal indicator red?
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).
How can hydrochloric acid turn red in color?
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.
What color would hydrochloric acid pH 1 turn universal indicator?
Hydrochloric acid at pH 1 would turn universal indicator red, indicating a strongly acidic solution.
What is the colour with universal indicator hydrochloride acid in stomach?
Universal indicator changes color to red in the presence of hydrochloric acid in the stomach, indicating a low pH.

What colour will appear when hydrochloric acid react to sodium hydroxide with a few drop of universal indicator?
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.
What color does base turn a universal indicator?
The color of a universal indicator in a basic solution is usually purple or blue.
What is colour of ethanol in universal indicator?
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.
What colour universal indicator turns to a neutral?
Green is the color that universal indicator turns to when it is neutral.
What color do alkalis turn universal indicator?
When universal indicator is put in water soluion of alkalis (base) it indicates significant blue colour.
What turns hydrochloric acid red?
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.
What color does universal indicator turn in deionized water?
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.
