Answer #1

NaOH is strong base and dissociates completely in to

Na+ and OH- ions.

NaOH ----------> Na+ + OH-

1 mole NaOH produce 1 mole OH- ion ( ratio 1:1 ).

Therefore, [OH-] = [ NaOH ]

Therefore, pOH = -log [OH-]

= - log ( 0.520 )

= 0.283.

Now, pH = 14 - pOH

= 14 - 0.283

= 13.71.

Ans = b = 13.7

A solution is prepared by dissolving 0.23 mol of formic acid and 0.27 mol of sodium formate in water sufficient to yield 1.00 L of solution. The addition of 0.05 mol of NaOH to this buffer solution causes the pH to increase slightly. The pH does not increase drastically because the NaOH reacts with the present in the buffer solution. The K, of formic acid is 1.8 x 10+ A formic acid B. sodium formate C water D. sodium E....
