A 50 ml aliquot of 0.05 M NaCN (Ka for HCN = 6.2* 10-10) is titrated with 0.1 M HCI. The reaction is CN + H, O* Calculate the PH after the addition of (a) zero ml (b) 10 ml (c) 25 ml (d) 26 ml of acid and draw the titration HEN +H,0 curve.​

Asuspension of yeast cells is being grown under anaerobic conditions such that glucose is degraded to ethanol and carbon dioxide. if one wishes to follow this process by monitoring the release of 14co2, at which positions in the glucose molecule would the 14c label need to be incorporated?
