Ph 1-14 color chart in each pack,and each pack is attached with a color comparison card, which indicate different Ph values correspond to specific colors.3. Different Ph content discoloration range is different, by comparing the color card ratio: the smaller the number, the stronger the acidity, and the larger the value, the stronger the alkalinity.Instructions:1.Test the solution: a. Take a small piece of test paper and place it on a watch glass or glass slide;b. Use a glass rod or plastic dropper with the test liquid to point it on the middle of the test paper;c.
