Red Litmus remains red in acid. It is normally used to test for bases. It turns blue in the presence of bases.
Stomach acid is acidic, so litmus paper would turn red when exposed to it.
Phenol is a weak acid, so it can turn blue litmus paper red, indicating its acidic nature. However, phenol does not significantly affect red litmus paper, as it is not a strong enough acid to change its color. Overall, phenol primarily affects blue litmus paper by turning it red.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
Blue litmus paper will turn to red because hydrochloric is an acid. In aqueous solutions,acid change blue litmus paper to red. In aqueous solutions,base change red litmus paper to blue.
yes, it does, regardless of the substance colour.
Depends on the litmus paper. Red litmus will not turn but blue litmus will turn redish pink.
Acid can't turn red litmus paperbur base canturn it blue .
In an acid solution the blue litmus paper become red.
Hydrochloric acid will keep litmus red - it needs alkali to turn it blue
Red!
if you are working with a strong acid the lithmus paper will turn red.
Because Vinegar is an acid, the litmus paper would turn red
Acid will turn litmus paper red.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
Litmus paper will turn red in dilute hydrochloric acid, indicating that the solution is acidic.
Litmus paper will turn red in the presence of sulfuric acid, indicating that the solution is acidic.
