pH Paper Pkg. Of 100

pH Paper Pkg. Of 100

Product Review (submitted on September 28, 2008):

I been working with acids and bases for quite some time now, and though this is not as precise as using a pH meter, it is a lot more accurate than the natural indicating solution of red cabbage. And if it answers your question, 7 is neutral, below seven is acidic, above 7 is basic.
