Ph Scale Red Litmus Paper

The blue paper changes to red indicating acidity somewhere between the ph range of 4 5 to 8 3.
Ph scale red litmus paper. Examples of litmus paper color changes. Common acids include include tartar sauce corn bacon and beer. Sulfuric acid is obviously acidic in nature. Bases turn red litmus paper blue.
These are the important points about the ph scale. Red litmus paper is meant to test only for an alkaline ph level. Initially litmus paper is either red or blue. In general litmus paper is red below a ph of 4 5 and blue above a ph of 8 3.
Red litmus paper can show a base with a ph greater than 8. It turns blue litmus paper red. Sodium hydroxide is a base. The ph is a measurment of how acidic basic a liquid is.
A ph scale reading of 8 indicates a weak base. If it comes in contact with an acidic or neutral substance it will remain red. A ph scale reading of 6 indicates a weak acid. The table shows the colour changes it can make.
Blue litmus paper can indicate an acid with a ph between 4 and 5 or lower. Is usually more reliable and comes as red litmus paper and blue litmus paper. It turns red litmus. When red litmus paper is placed into a basic substance it will turn blue.
Acids turn blue litmus paper red.
