A chemistry graduate student is given 100. mL of a 0.40M nitrous acid (HNO,) solution. Nitrous acid is a weak acid with K 4.5 x 10. What mass of -4 NaNO, should the student dissolve in the HNO, solution to turn it into a buffer with pH =3.16? %3D You may assume that the volume of the solution doesn't change when the NaNO, is dissolved in it. Be sure your answer has a unit symbol, and round it to 2 significant digits. x10 Submit Assignment Continue 2021 McGraw Hill LLC. AlI Rights Reserved.

A student is titrating a 100 mL of 0.50 M solution of hydrofluoric acid (HF) with 1.0 M strong base (NaOH). a) at the equivalence point, what ions/compounds will be present in the solution? A complete answer will also be specific as to what ions/compounds are not present in solution. b) calculate the pH at the equivalence point.

in the following reaction:Ca(OH)2(s) + 2H+(aq) 2H2O(1) + Ca2+(aq)if add the. drops of [HCI], the system will shift to

Determine the pH during the titration of 21.9 mL of 0.277 M perchloric acid by 0.206 M sodium hydroxide at the following points: (1) Before the addition of any sodium hydroxide (2) After the addition of 14.8 mL of sodium hydroxide (3) At the equivalence point (4) After adding 35.4 mL of sodium hydroxide
