a 2.00l buffer contains 1.00 mol HNO3 mixed with 1.00mol NaNO2

a. write the relevant ionization equation for this buffer.
b. determine its pH
c. determine the new pH if 1.00g of NaOH is added to the buffer

You work this problem much like the one when your name was Mickey. Post your work if you get stuck and I will help you through it.
