Why water must be added before you add the iodine solution at the slide?
Water must be added before the iodine solution to create a dilute environment that allows the iodine to spread evenly across the specimen. This prevents the iodine from clumping and ensures better visibility of cellular structures under the microscope. Additionally, water helps to preserve the specimen's natural shape and prevents damage that could occur from direct application of the iodine.
Why iodine oinment called non-staining?
Iodine ointment is called non-staining because it does not leave a permanent mark or discoloration on surfaces or fabrics it comes into contact with. This makes it easier to use without worrying about staining clothes or other items.
Can food coloring be used to substitute methylene blue in staining cheek cells?

How does Lugol's iodine differ from Gram's iodine?
Lugol's iodine is a solution of iodine and potassium iodide, commonly used as a disinfectant and in nutritional applications, while Gram's iodine is a specific formulation used in the Gram staining procedure for bacterial classification. Gram's iodine acts as a mordant, enhancing the retention of the crystal violet dye in Gram-positive bacteria. In contrast, Lugol's iodine is more versatile and used primarily for thyroid function assessments and antiseptic purposes. Their concentrations and intended uses distinguish them significantly in laboratory and medical settings.
What is the difference between Iodine bought in a pharmacy and the Iodine stain solution?
The iodine stain solution you're referring to might be Lugol's iodine. This is iodine and potassium iodide in water. The product available in a pharmacy is tincture of iodine which is iodine and potassium iodide in ethanol and water. Please see the links.
What is the difference between strong iodine solution and weak iodine solution?
their color
Is milk a concentrated or dilute solution?
Diluted milk is milk that is diluted with water or other substance
Differences between lugols iodine and grams iodine?
Lugol's Iodine = 20g Potassium Iodide + 10g Iodine dissolved in 1L H2O Gram's Iodine = 6.7g potassium iodide + 3.3g Iodine dissolved in 1L H2O Recipe's taken from Flinn Scientific Catalog I have on campus. Looks to me as Gram's is just a dilute version of Lugol's. Same ratio of KI:I just less of it. Couldn't tell you much about differences in application however.
Is there a solution of alcohol and iodine?
Yes, a solution of alcohol and iodine is known as tincture of iodine. It is commonly used as an antiseptic for disinfecting wounds and skin before surgery. However, it should be used with caution as it can cause skin irritation and staining.
How do you prepare 1 percent iodine solution?
To prepare a 1% iodine solution, you can mix 1 part iodine with 99 parts water (for example, 1 mL iodine to 99 mL water). Ensure proper handling and measuring equipment to accurately dilute the iodine. Remember to always label the solution properly for safety and tracking purposes.
What effect did staining with iodine solution have on the cells?
Staining with iodine solution caused the cells to change color based on the presence of starch. Starch-containing cells turned blue-black, while cells lacking starch remained unchanged. This allows for easier visualization and differentiation of cell types under a microscope.
What does lugol's iodine?
it is iodine and potassium iodide solution It's a orange colored solution that consists of Iodine and Potassium Iodide and is used to test a substance for starch. If the color of the solution turns black when put on/in the substance, then the substance is positive for starch.
Preparation of 0.1n iodine solution?
According to Kodak: For a 0.1 Normal (0.1N) solution of iodine (I2), in 1 L volume flask, dissolve 40 g potassium iodide in 25 mL water. Next, add 12.7 g iodine (I2) and dilute to 1 L. Note that a 0.1N solution is not the same as a 0.1M solution. For iodine 0.1N is 0.05M.
What can be used to stain alveolar mucosa so as to demarcate the mucogingival junction how to prepare the reagent used for this staining?
schiller's iodine solution
Can a dilute iodine solution be used to distinguish between amylose and amylopectin?
No, a dilute iodine solution cannot be used to distinguish between amylose and amylopectin. Iodine will react with both amylose and amylopectin to form a blue-black complex, showing that both contain starch. Other methods, such as enzymatic digestion or chromatography, are typically used to separate amylose and amylopectin.
Is iodine solution ionic?
A solution of iodine is covalent.
Is iodine a basic stain?
No, iodine is not a basic stain. Iodine is commonly used in Gram staining to identify bacteria as either Gram-positive or Gram-negative based on their cell wall composition. It acts as a mordant in the staining process and helps to fix the crystal violet stain in Gram staining.
