Foolproof pH test to determine if a solution is acidic or alkaline.
A foolproof pH test to determine if a solution is acidic
The Blue Litmus test paper does not come with a color chart as it cannot provide you with a defined pH value
The test strip will turn red if dipped into an acidic solution (pH <7)
It will remain unchanged in an alkaline solution
We have tested the blue litmus with multiple pH buffers
The blue paper is blue at pH 8
At pH 7, the sample is maybe just a little red
The real change to red seems to start with pH 6
5 and lower
Neutral Litmus test paper tests for Neutrality of a solution, or its acidity or alkalinity
The test strip will turn red if dipped into an acidic solution (pH <7) or blue if dipped into an alkaline solution (pH >7)
Red Litmus test paper is a foolproof pH test to determine if a solution is alkaline
The test strip will turn blue if dipped into an alkaline solution (pH >7)
