A student needs to prepare a buffer solution with a pH of 4.67. Assuming a pkg of 4.69, how many ml of 0.1 M NAOH would need to be added to 18.0 ml of 0.1 M HB to prepare this buffer? Please include a proper (abbreviated) unit. HINT : Use pH = pk3 + log ([B minus]/[HB]) or, if concentrations are the same, pH = pk, + log (Volume of OH minus/ (Volume of HB minus Volume of OH minus) %3D

The Mole Concept Sulfur compounds are converted to HSO, while NO, compounds are converted to HNO3, and NH3 reacts with these acids to form ammonium salts. Since acidifying deposition involves different substances, one process that naturally occurs is nitrification via bacterial conversion according to: (MN= 14.01 g/mol. Mo-16.00 g/mol, MH = 1.008 g/mol, Ms = 32.07 g/mol) NH + 20, → NO, + 8;0+ 28* A. If 10.15 g of NH. was found in the soil, how many ions of NH.was present initially? B.
