Description
NOTE:This paper does not apply to buffer solutions and very weak acid-base solution concentration lower than 0.01%se note that solutions with a pH of 5.5 will result in a yellow colored test strip that resembles the original color of the dry stripe in a cool, dry place away from sunlightructions: 1. Take one strip and dip it into the solution you would like to measure. The color of your strip will change immediately.2. Quickly match this color against the color chart on the inside of package to obtain the pH in 15 seconds. Do not wait or let the strip dry!3. The number next to the color on the chart is your pH. The pH scale ranges from 1 (very acidic) to 14 (very basic), 7 is neutralription:Testing Range: 1-14Overall Size: 55x9mm / 2×0.35 inch (L*W)pH test strips are widely applied to industrial chemical testing, science education, lab use, drinking water, swimming pool, spa, aquarium, hydroponics and classroom analytical chemistryage Content: 1 x pH Test Paper KitCommon Uses of pH :Acid Rain, pH = 4.3 – 5.6 Based Glass Cleaner, pH = 10Battery Acid, pH = 1Beer, pH = 4.5Bleach, pH = 12.6Drain Cleaner, pH = 14Drinking Water, pH = 6.5 – 8.5Fruit Juice, pH = 2 – 5.5Gastric Acid, pH = 1.5 – 3.5Lemon Juice, pH = 2Milk, pH = 6.8Milk of Magnesia, pH = 10.5Oven Cleaner, pH = 13Pure Water, pH = 7Saliva, pH = 6.2 – 7.4Sea Water, pH = 8Soft Drinks, pH = 2 – 4, pH = 7 – 10Tea, pH = 4.9 – 7.2Urine, pH = 4.6 – 8Vinegar, pH = 3.1
