The table below shows the most common prefixes and their relative magnitudes. Note that web browsers do not support use of superscripts and subscripts very well, so the notation 10^2 means 10 to the power of 2, or 10 squared. Similarly, the notation 10-2 should be read as 10 to the power of -2.
Litmus paper is red, litmus paper is blue, put these papers in a liquid or a gas and its hydrogen ion concentration will shine true. Litmus paper, or pH paper, is a tool that scientists use to discover whether a liquid or gas is an acid or a base.You can use litmus paper to see whether bleach is an acid or a base by examining what color the paper turns.n the other hand, a blue piece of litmus paper put in an acid will turn red. If you have a gas or a liquid with a neutral pH level, neither the red nor blue litmus paper will change color when introduced to the substance in question.
For instance, ammonia gas, which is alkaline, colors the red litmus paper blue. Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5-8.3 at 25 Â°C (77 Â°F). Neutral litmus paper is purple.
