A. A buffer solution that is 0.431 M inHClO and 0.431 M inNaClO has a pH of 7.46.

(1) The addition of 0.01 mol ofH₃O⁺ to 1.0 L of this bufferwould cause the pH to _(increase slightly, increase by 2units,decrease slightly,decrease by 2 units,not change.)

(2) The capacity of this buffer for addedOH^- could be increased by the additionof 0.147 molÂ Â _(of the weakacid,of the salt.)

B. How many grams of solid sodiumfluoride should be added to 2.00L of a 5.23Ã—10^-2M hydrofluoricacid solution to prepare a buffer with a pH of3.816 ?

grams sodium fluoride=Â Â g.
C.How many grams of solid ammoniumbromide should be added to 2.00 Lof a 0.287 M ammonia solution toprepare a buffer with a pH of 8.740?Â Â
