For agarose gel electrophoresis, a TBE buffer can be used at a concentration of 0.5x (1:10 dilution of the concentrated stock). Dilute the stock solution by 10x in deionized water. Final solute concentrations are 45 mM Tris-borate and 1 mM (millimolar) EDTA. The buffer is now ready for...
How to calculate molarity of HCl from titration? Acid-Base Titration: The method of titration is an analytical procedure that allows a scientist to use a known concentration titrant (solution) to determine the concentration or quantity of an analyte present in a sample. The titrant and analyte ...
How to use: Dilute the potency of the liquid by mixing one part ACV into 2 or 3 parts water to avoid skin irritation and burns. Apply this solution on the pigmented areas for a few minutes and then rinse it off with lukewarm water. ...
Dow's process is a method to prepare phenol. The reactant chlorobenzene is heated with aqueous sodium hydroxide at temperature 623K and 300atm to get sodium phenoxide ion. Then in the next step sodium phenoxide ion is treated with Dilute HCl which gives the final product as phenol. What is...
