Changes color from red to blue when conditions change from acidic to alkaline. Litmus paper is the best-known indicator paper. PlatformProducts for pH determination ParameterpH Detection limitpH - 5.0–8.0 Color changepH - red → blue Length70 mm ...
The pH scale ranges from zero to 14, with a pH of 7 being neutral, a pH less than 7 being acidic, and a pH greater than 7 being alkaline. Ammonia gas turns red litmus paper blue because it has a pH of 11.6. Milk of magnesia is slightly less alkaline, with a pH level of around...
Red litmus paper is specifically designed to test for acidity. When the red litmus paper comes into contact with an acidic solution, it remains red. However, when it is exposed to an alkaline solution, it turns blue. This simple color change allows chemists to quickly determine the pH of a...
paper turns blue when it comes into contact with an alkaline (basic) liquid with a pH over 8.3, but stays red if it comes into contact with an acid. Either type of litmus paper can be used to test any substance, just so long as you remember that red means acidic and blue means ...
