Litmus paper is an indicator that changes color when affected by the pH of certain chemicals. There are two colors to test the general pH of a solution.
Alkaline solutions (bases) turn red litmus paper blue.
Acidic solutions (acids) turn blue litmus paper red.
Acid turns litmus paper red.
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.
An acid will change litmus paper to red.
Nothing, red litmus paper changes in the presence of an acid not a base, blue litmus paper turns red with nitric acid
An acid turns blue litmus paper red. This is because the acid donates a proton (H+) to the water in the litmus paper, changing the pH and causing the litmus paper to change color.
Lemon juice is an acid therefore, it turns blue litmus paper red and red litmus paper remains red
Acid turns litmus paper red.
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.
An acid will change litmus paper to red.
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.
Acid will turn litmus paper red.
Nothing, red litmus paper changes in the presence of an acid not a base, blue litmus paper turns red with nitric acid
An acid turns blue litmus paper red. This is because the acid donates a proton (H+) to the water in the litmus paper, changing the pH and causing the litmus paper to change color.
blue litmus paper turns to red when its in contact with acid
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
carbon dioxide turns wet blue litmus red because carbon dioxide dissolves in water to form weak dibasic acid called carbonic acid
Acid turns blue litmus red and maintains red litmus at the same color.
