Blue Litmus Paper Ph Scale

A ph scale reading of 8 indicates a weak base.

Blue litmus paper ph scale.

Examples of litmus paper color changes. A ph scale reading of 6 indicates a weak acid. A higher ph means it is more alkaline or a stronger base. Litmus paper comes as red litmus paper and blue litmus paper.

A blue litmus paper turns red in acids while a red litmus paper turns blue in basic solutions. It turns red litmus. Sulfuric acid is obviously acidic in nature. Litmus indicator solution turns red in acidic solutions blue in alkaline solutions and purple in neutral solutions.

It turns blue litmus paper red. The table shows. Bases turn red litmus paper blue. Sodium hydroxide is a base.

Chemistry classes will often use a litmus test to identify acids from bases. Ph scale diagram with corresponding acidic or alcaline values for common substances food household chemicals. A lower ph means something is more acidic also known as a stronger acid. 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. Colorful vector illustration in flat style isolated on white background. Acids turn blue litmus paper red. Note that 8 3 is alkaline red litmus paper can indicate alkalinity with a change to blue.

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. The blue paper changes to red indicating acidity somewhere between the ph range of 4 5 to 8 3.
