Chemistry

I have a mixture consisting of 0.180 M nitrous acid, and 0.150 Msodium nitrite. NOTE: pKa (nitrous acid) = 3.14. 7.

First, I add 2.00 mL of 0.500 M HCl to 20.00 mL of the original(sodium nitrite / nitrous acid) mixture. Assuming these volumes areadditive, make an ICE table and:

a) Write the corresponding balanced reaction, specifying ALL ofits relevant reactant and product components.

b) Calculate how many moles of each relevant reaction componentare initially present.

c) Calculate the change in the moles of each relevant reactioncomponent.

d) Calculate the moles of each relevant reaction component atequilibrium.

e) Calculate the new molar concentration of nitrite anions.

f) Calculate the new molar concentration of nitrous acid.

g) Calculate the new pH of the resulting mixture.
