1a.A buffer is prepared by dissolving 2.753 g sodium acetate in 125.0 mL of 0.1091 M acetic acid(Ka = 1.75 x 10-5).Calculate the pH of this buffer.b.An additional 1.000 g of sodium acetate is added to the buffer prepared above. Calculate the new pH.c.Calculate the Ka for ammonium hydroxide, using the Kb value and Kw.d.Determine the moles of HCl present in 15 drops of 6M HCl if 20 drops = 1.0 mL.Solution to 8178070Let us first Calculate [CH3COOH] & [CH3COONa -]Mols CH3COOH = 0.125 L x 0.1091 mols/L = 0.0136 MMols CH3COONa - = 2.753/82.03 = 0.0335 moles125.0 ml (= 0.125L) contains =...
