Blue Litmus Paper Ph Scale

In general litmus paper is red below a ph of 4 5 and blue above a ph of 8 3.

Blue litmus paper ph scale.

Bases turn red litmus paper blue. Litmus indicator solution turns red in acidic solutions blue in alkaline solutions and purple in neutral solutions. Chemistry classes will often use a litmus test to identify acids from bases. A higher ph means it is more alkaline or a stronger base.

Blue litmus paper can indicate an acid with a ph between 4 and 5 or lower. A ph scale reading of 6 indicates a weak acid. A lower ph means something is more acidic also known as a stronger acid. Colorful vector illustration in flat style isolated on white background.

Sodium hydroxide is a base. Initially litmus paper is either red or blue. Litmus paper color chart. Ph scale diagram with corresponding acidic or alcaline values for common substances food household chemicals.

To test the ph of a substance dip a strip of litmus paper into the solution or use a dropper or pipette to drip a small amount of solution onto the litmus paper. Sulfuric acid is obviously acidic in nature. It turns blue litmus paper red. Litmus paper comes as red litmus paper and blue litmus paper.

The blue paper changes to red indicating acidity somewhere between the ph range of 4 5 to 8 3. The table shows. A ph scale reading of 8 indicates a weak base. A blue litmus paper turns red in acids while a red litmus paper turns blue in basic solutions.

It turns red litmus. Note that 8 3 is alkaline red litmus paper can indicate alkalinity with a change to blue.
