Acidic or alkaline? Now you can distinguish between what paper or board is suitable for conservation with the stroke of a pen. The indicator solution of chlorophenol red will turn a shade of purple on paper with a pH of 6.5 or higher. Any other color would indicate a pH lower than 6.5, thereby acidic and unsuitable for artwork that is meant to last. - 追加情報
