in the lab we are doing the chemoselective reduction of 3-nitroacetophenone using sodium borohydride , a question our lab demonstrator asked us to do for the lab report was to draw the mechanism of reduction with NaBH4 but show all steps. i.e 1 x NaBH4 reduces 4 x carbonyls and not to stop when one mole of carbonyl is reduced and to also show alkoxide salts formed at each step...

A 0.200 M solution of HCl is added to a solution containing 0.150 moles of sodium phosphate (Na3PO4). The resulting solution is then diluted to exactly 1.00 L, at which time the pH was found to be pH 8.00. What is the concentration of H2PO4- in the solution? For phosphoric acid, Ka1 = 7.11 x 10-3, Ka2 = 6.32 x 10-8, and Ka3 = 7.1 X 10-13.

a) Buffer solutions with a pH values of around 10 are prepared using sodium carbonate (Na2CO3) and sodium hydrogen carbonate (NaHCO3). What is the pH of a solution of 10.0g each of the two salts in enough water to make 0.250 L of solution? pKa2= 10.33 b) By how much does the pH change when 3.5mL of 6.0 M HCl is added? c) By how much does the pH of the solution change when 0.92 g of NaOH is added?
