1393-92-6 Usage
Description
Litmus is a natural pigment that serves as a rough indicator of the acidity or basicity of a solution. It is a water-soluble dye extracted from certain lichens and changes color when in contact with acids and alkalis. Above a pH of 8.3, it appears blue, and below a pH of 4.5, it appears red. Due to its broad range of color change, it is not suitable for precise work but is commonly used in both solution and as litmus paper.
Uses
1. Used in Chemical Laboratories:
Litmus is used as a pH indicator for determining the acidity or alkalinity of a solution. It is particularly useful in educational settings and basic chemical analysis, where precise measurements are not required.
2. Used in Environmental Testing:
Litmus is employed as a simple and cost-effective method to test the pH levels of natural water sources, such as rivers, lakes, and groundwater, to assess their suitability for various purposes.
3. Used in Industrial Processes:
In certain industries, litmus is used as a quality control tool to monitor the pH levels of various solutions, ensuring that they remain within the desired range for optimal product performance.
4. Used in Medical and Diagnostic Applications:
Litmus paper is utilized in medical and diagnostic settings to test the acidity or alkalinity of bodily fluids, such as urine, sweat, and saliva, which can provide valuable information about a patient's health.
5. Used in Educational Purposes:
Litmus is often used in educational institutions to teach students about the concept of pH and the importance of understanding the acidity or alkalinity of solutions in various scientific contexts.
6. Used in Horticulture and Agriculture:
Litmus can be employed by gardeners and farmers to test the pH of soil and water used for irrigation, helping them to maintain optimal growing conditions for plants and crops.
7. Used in Food and Beverage Industry:
In the food and beverage industry, litmus can be used to test the pH of various products, such as beverages, sauces, and dressings, to ensure that they meet the desired acidity or alkalinity levels for taste, shelf life, and safety.
Check Digit Verification of cas no
The CAS Registry Mumber 1393-92-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,9 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1393-92:
(6*1)+(5*3)+(4*9)+(3*3)+(2*9)+(1*2)=86
86 % 10 = 6
So 1393-92-6 is a valid CAS Registry Number.
