Red, remember blue base, acid red
hydrochloric acid usually has pH 1 which turns litmus Red
Hydrochloric acid will keep litmus red - it needs alkali to turn it blue
Depends on the litmus paper. Red litmus will not turn but blue litmus will turn redish pink.
Blue litmus paper would be used and if the chemical is an acid the litmus paper would turn red.
Perhaps some red dye? But hydrochloric acid turns blue litmus paper red.
It is because the red litmus paper only changes its color (from red to blue) when exposed to any basic substance. Hydrochloric acid is acidic, thus there is no change in the color of the red litmus paper, although the acid would change the color of the blue litmus paper (pH paper that tests for acidity; changes from blue to red in the presence of acid)

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.

Actually, some acids do burn litmus paper. Hydrochloric acid, for example, can burn paper, but the litmus on litmus paper shields the paper from the acid. Sulfuric acid, however, has dehydration properties, and would suck the water right out from the paper, charring it instantly.
an acid turns the litmus paper red.
Acid: Red litmus
will remain red
