Why wouldn’t we want to spot an aqueous solution onto the silica gel?The standard curve to determine the amount of betacyanin is shown below. You extracted a red pigment from a beet disc (the mass of a disc is 2 g) using 10 ml of 20% ethanol solution. You measured absorbance of the solution above the beet disc every minute for a total time of 20 minutes. The increase in absorbance was linear during a period of time from 1 min to 10 min. The absorbance at 10 min was 0.8. Calculate the amount of betacyanin extracted from 1g of a beet tissue per minute. Explain your calculations. You can use Excel or a calculator.
