Neutral Litmus test paper tests for Neutrality of a solution, or its acidity or alkalinity. The Neutral 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) or blue if dipped into an alkaline solution (pH >7).
