A 350 Ml BUFFER SOLUTION WAS PREPARED BY A CHEMIST BY MIXING A 0.135 m ch3cooH AND 0.100 m cHcooK. ACCIDENTALLY, you added 12 mL of an unlabeled solution to the buffer solution during the experiment. your groupmate, later on, identified this to be 1.5 M HCL whcih was mistakenly left unlabeled when she went out to urinate. compute the following: use the pKb value of 7.62   1. what is the number of moles of HCL contanied in the 12 Ml solution added? 2. what is the number of moles of CH3COOH whcih participated in the reaction upon adding 12 ml of 1.5 M HcL? 3. what is the number of moles of CH3COOk which participated in the reaction upon adding 12 Ml of 1.5 M hcl? 4. what is the pH of the original buffer solution?  5. what is the ph of the final buffer solution  6. what is the change in pH in percentage
