test for bases.
yes a blue litmus paper turns red when put into an acid
blue litmus paper turns to red when its in contact with acid
Red litmus paper is used to check for basicity. It turns blue when exposed to bases. Blue litmus paper is used to check for acidity. It turns red when exposed to acids.
Acid turns litmus paper red.
the red litmus paper turns to blue
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
The red litmus paper will remain red in acetic acid. Acetic acid is a weak acid and does not change the color of red litmus paper.
Red litmus paper is used to test for acids. If the red litmus paper turns blue when dipped in a substance, it indicates the presence of an acid.
Red litmus paper remains red when dipped into an acid. Blue litmus paper will turn red in an acid. Similarly, Blue litmus remains blue in a base. Red litmus turns blue in a base.
An acidic solution will change blue litmus paper to red and basic solutions change red litmus paper to blue
Lemon juice is an acid therefore, it turns blue litmus paper red and red litmus paper remains red
