it turns red colour
Turmeric (curcumine) remain yellow in acidic solutions.
Hydrochloric acid: yellow color Sodium hydroxide: brown color Sugar: unchanged
Universal indicator will turn red or pink in dilute hydrochloric acid.
it turns yellow
The indicator turns pink when an excess of hydrochloric acid has been added in a titration.
Hydrochloric acid is a clear, colorless liquid with a strong, pungent odor. It is also highly corrosive and can cause burns upon contact with skin. You can identify hydrochloric acid by its distinctive smell and its ability to dissolve certain metals like zinc and magnesium.
Universal indicator changes to red/orange when hydrochloric acid is added, indicating that the solution is acidic.
If it is adulterated a black colour will be formed :D
Methyl red is an adequate indicator.
Turmeric paper contains curcumin, a natural pH indicator that changes color in response to acidity. When hydrochloric acid is applied, the acidic environment causes curcumin to undergo a chemical change, resulting in a red coloration. This color change indicates the presence of acid, demonstrating the pH-sensitive properties of turmeric.
Hydrochloric acid at pH 1 would turn universal indicator red, indicating a strongly acidic solution.
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.
