To 2 significant figures, what mass of must be added to 0.650 L of a 0.120 M solution of to give a buffer solution with a pH of 9.08? Assume a negligible change in volume as the solid is added. The of is .
A buffer solution is prepared from equal volumes of 0.200 M acetic acid and 0.600 M sodium acetate. The of acetic acid is .
Is the solution acidic, neutral, or basic?
Saccharin, , is a weak acid (). If a 0.250 L solution with a buffered pH of 5.48 is prepared from g of sodium saccharide, , what is the equilibrium concentration of saccharin in the solution?
