You need to make an injection using the Atropine hydrochloride at a concentration of 0.03 mol/L. The drug Atropine (a weak base), with a pka value of 9.6, has a solubility of 0.02 mol/L. Calculate the precipitation pH, and find if this drug will precipitate at the injection site pH 7.2? ApH K,[H,O"| For weak acid Precipitation pH is given by S-So p = pka + log- So B-2.3C (K,+ [H,O" ]y For weak base Precipitation pH is given by So p= pka + log; 85-So pil + pou - 14 and phu - plv - pki Select one: O a. precipitation pH is 9.9; No, it will not precipitate b. precipitation pH is 9.6; Yes, it will precipitate c. precipitation pH is 9.9; Yes, it will precipitate d. precipitation pH is 9.6; No, it will not precipitate
