Blue Litmus Paper - 100 strips

Litmus paper is a crucial supply for any laboratory, and is used in classrooms of all grade levels.  These one hundred blue strips of litmus paper can be used to determine the pH category of a substance.  By way of a mixture of dyes extracted from lichens, they tell you whether the substance is acidic or basic.  If the substance is a base, the paper remains blue.  If the substance is acidic, the paper will shift its color to red, allowing you to know whether you’re dealing with an acid or a base in your experiments.  The paper will also turn purple in the presence of a neutral substance.  A highly useful tool for basic chemistry.

Features:

• Determines whether a substance is an acid or a base
• Turns from blue to red upon contact with an acid
• Remains blue upon contact with a base
• Purple upon contact with neutral substances
• 100 strips included
• Great for experiments

This was good for helping my 5th graders learn about acids and bases. I wish you also carried red litmus and PH paper
