Please refer to the explanation below.

Explanation:

Acids turn methyl orange red and also litmus paper red.

To see that in a lab, take a few drops of diluted hydrochloric acid #(HCl)# using a pipette, and drop it into a solution of methyl orange #(C_14H_14N_3NaO_3S)#. You should see the solution turn red.

With litmus paper, take a piece of blue litmus paper by hand and dip it into a solution of aqueous hydrochloric acid #(HCl)#. You should see it turn red. With red litmus paper, this has no effect, and the colour stays red.
