Determination of hydrolyzable tannins in the fruit of

Capillary electrophoretic analyses were also attempted and it was found that CZE (25 mM Na2B4O7 5 mM NaH2PO4 pH 7 0) was an efficient method for the separation of gallotannins while an MEKC method (25 mM Na2B4O7 5 mM NaH2PO4 20 mM SDS pH 7 0 and 10% acetonitrile) provided a better separation for most of the tannins examined

Buffer solution pH calculations (video)

So let's go ahead and write that out here So we have our pH is equal to 9 25 minus 0 16 And so that comes out to 9 09 So the pH is equal to 9 09 So remember for our original buffer solution we had a pH of 9 33 So we added a lot of acid the pH went down a little bit but not an extremely large amount

Laboratory Solution • Basic concepts of preparing

molarity is liters not milliliters or some other unit Also note that one liter of solution contains both the solute and the solvent Molarity therefore is a ratio between moles of solute and liters of solution To prepare laboratory solutions usually a given volume and molarity are required To determine molarity the formula weight or molar mass of the solute is needed The following

buffer solutions

Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt A common example would be a mixture of ethanoic acid and sodium ethanoate in solution In this case if the solution contained equal molar concentrations of both the acid and the salt it would have a pH of 4 76 It wouldn't matter what the concentrations were as long as they were the same

Acid salt

Acid-base property of the resulting solution from a neutralization reaction depends on the remaining salt products A salt containing reactive cations undergo hydrolysis by which they react with water molecules causing deprotonation of the conjugate acids For example the acid salt ammonium chloride is the main species formed upon the half neutralization of ammonia in hydrochloric acid solution:
