Saturated KCl precipitation is often used in DNA extraction for molluscan taxa. Molluscs produce a polysaccharide rich mucus that interferes with the reagents involved in DNA extraction.
The KCl saturated solution is used right after the digestion step: about 1/4th of the volume of the digestion solution is added to the sample. Samples are then centrifugated at 14rpm for 15 minutes. The pellet formed will contain the polysaccharides and non digested tissue. The supernatant is extracted from the tube and used in the next steps of the DNA extraction.
What else can I help you with?
What mass of KCl would be needed to form a saturated solution if the KCl was dissolved in 200 g of water at 80 C?
The solubility of KCl in water at 80°C is approximately 380 g/L. To form a saturated solution, you would need to dissolve 380 g of KCl in 1 L (1000 g) of water. Since you are using 200 g of water, you would need 76 g of KCl to form a saturated solution.
What is KCl?
KCl is the chemical formula for potassium chloride, a salt commonly used as a supplement in potassium-deficient diets or for medical purposes. It is also used in food processing and manufacturing, as well as in medical settings to treat certain conditions.
What temperature would KCL solid be most soluble?
Short answer: You don't say what you are dissolving KCl (potassium chloride) in but we'll assume it is water. Salts like KCl dissolve in water better at higher temperatures. Boiling water (100C or 212 F) is the hottest you can get water without confining it and increasing the pressure. So 212F or 100C is the temperature that KCl is most soluble in water. Longer answer: As you add KCl to water the boiling point of the solution becomes lower. So the real maximum solubility temperature (assuming no pressurization) is less than 212 F (100 C). The easiest way to measure this would be to mix highly purified KCl with highly purified water and boil it to see what the boiling temperature is. You must add enough KCl so that even at boiling temperature you still have some solids left that way you will have a saturated solution which will have as much KCl dissolved as the water can hold.
What is the IUPAC name for KCl?
KCl is 'potassium chloride'.
What is the empirical formula of KCl?
Potassium chloride is a ionic lattice which is made out of potassium ions and chloride ions. Therefore, separate 'molecules of this compound do not exist. The empirical formula itself is KCl which is used also as the chemical formula for the compound.
When 5 grams of KCl are dissolved in 50. grams of water at 25C the resulting mixture can be described as?
This is a solution of 10 g KCl/100 g water.
What mass of KCl would be needed to form a saturated solution if the KCl was dissolved in 200 g of water at 80 C?
The solubility of KCl in water at 80°C is approximately 380 g/L. To form a saturated solution, you would need to dissolve 380 g of KCl in 1 L (1000 g) of water. Since you are using 200 g of water, you would need 76 g of KCl to form a saturated solution.
50 g of potassium chloride (KCl) are added to 100 mL of water. All but 10 g of the KCl dissolves. Which equilibrium situation becomes established in the resulting solution?
The remaining 10 g of KCl forms a saturated solution in water, meaning the solution is in dynamic equilibrium with solid KCl dissolving and KCl ions re-crystallizing at the same rate. The resulting solution will contain both dissolved K+ and Cl- ions in equilibrium with undissolved KCl crystals.
What type of solution is it if 25g KCl are dissolved in 100g of water at 30 degrees celsius?
This would be considered a saturated solution if all 25g of KCl are completely dissolved in the 100g of water at 30 degrees Celsius.
Why KCl saturated with AgCl is used in Silver Silver chloride electrode?
KCl saturated with AgCl is used in the Silver-Silver chloride electrode because the presence of AgCl helps maintain a stable potential and ensures reproducibility of the electrode. The AgCl layer also provides a constant concentration of Ag+ ions at the electrode surface, which is essential for the electrode's performance in electrochemical measurements.
Why KCl is used as the standard for verification of cell constant?
a verification code is used to validate that a system complies with the requirements
