Blue Litmus Test Paper Paper Test PH Test Stick 100 strips Type Alkali Acid Measurement Water Quality Science Experiment

Description

Blue litmus paper is primarily used to detect acidic solutions. It turns red when the pH is below 5.4. If the pH is above 5.4, the paper will not change color, thus it cannot be used to determine the exact pH of an acidic solution. Strong oxidizing agents may cause the paper to fade. Store it in a dry, dark place. To detect acidic gases, moisten the blue litmus paper with distilled water and expose it to the gas. A color change will indicate the gas’s properties. Material: paper Box size: about 6.6x3x1.5cm 2.6×1.18×0.59in Test paper size: 6×0.9cm 2.36×0.35in Color:As Pictures Package Included: 100 Strips Box Product use: Detect the acidity and alkalinity of gaseous or liquid substances. It can be used to test amniotic fluid, cosmetics, soil, laundry detergent, fruit, etc. Main use: Mainly used to quickly determine the acidity and alkalinity of the solution. When encountering alkaline solution (pH 8), the red litmus paper turns blue, and when encountering acid solution (PH 4.5), the blue litmus paper turns red. When the pH value of the solution is between 4.5-8.0, the red litmus and blue litmus papers will not change color. 1. Simple and easy to use: Both acid-base test paper and litmus test paper are very easy to use, without complicated operation steps, just immerse the test paper in the liquid to be tested. 2. High accuracy: Both acid-base test paper and litmus test paper can provide fairly accurate results. Can help you accurately understand the pH of the liquid. Portability: This type of test paper is very light and easy to carry. Whether you are in the laboratory or outdoors, you can easily perform a pH test. Low Price: Compared with some high-tech measuring equipment, acid-base test paper and litmus test paper are very cheap. They are an absolutely affordable choice for laboratories and numerous industrial processes. 5. Wide range of use: Acid-base test paper and litmus test paper can be used to detect the pH of various liquids, including water, urine, wine, beer, soapy water, etc. Widely used, covering many areas of life.   Blue litmus paper detects acidic solutions, turning red below pH 5.4. It doesn’t indicate exact pH and won’t change color above pH 5.4. Strong oxidizing agents may cause fading. Store in a dry, dark place. For acidic gases, moisten with distilled water before exposure. Specifications: Paper material, box size 6.6x3x1.5cm, test paper size 6×0.9cm. Includes 100 strips. Uses: Detects acidity/alkalinity of gases or liquids (e.g., amniotic fluid, cosmetics, soil, detergents, fruit). Primarily for quick determination of solution acidity/alkalinity. Red litmus turns blue in alkaline solutions (pH 8), and blue litmus turns red in acid solutions (pH 4.5). No color change occurs between pH 4.5-8.0.
