Universal Indicator turns concentrated HCl red because Universal Indicator turns strong acids reds.
Litmus paper would turn red in the presence of hydrochloric acid, indicating acidity.
Hydrochloric acid at pH 1 would turn universal indicator red, indicating a strongly acidic solution.
Hydrochloric acid will keep litmus red - it needs alkali to turn it blue
The red litmus paper will turn blue when dipped in hydrochloric acid. This is because hydrochloric acid is acidic, and acids turn blue litmus paper red.
Depends on the litmus paper. Red litmus will not turn but blue litmus will turn redish pink.
Litmus paper would turn red in the presence of hydrochloric acid, indicating acidity.
Hydrochloric acid at pH 1 would turn universal indicator red, indicating a strongly acidic solution.
Hydrochloric acid will keep litmus red - it needs alkali to turn it blue
The red litmus paper will turn blue when dipped in hydrochloric acid. This is because hydrochloric acid is acidic, and acids turn blue litmus paper red.
it would turn green with a hint of blue.
Depends on the litmus paper. Red litmus will not turn but blue litmus will turn redish pink.
Universal indicator will turn red or pink in dilute hydrochloric acid.
Acid
Hydrochloric acid will turn pH paper red or pink when a few drops are added. This color change indicates that the acid is acidic, with a pH typically below 4.
hydrochloric acid usually has pH 1 which turns litmus 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.
Methyl orange and methyl red both shows red color in a HCl solution where pH is lesser than 4.71.
