What amount of solid NaOH must be added to 1.0 L of a 0.12 M
H2CO3 solution to produce a solution with [H+]= 3.0×10−11 M ? There
is no significant volume change as the result of the addition of
the solid.

1. What quantity (moles) of NaOH must be added to 1.0 L of 2.1 M
HC2H3O2 to produce a solution buffered at pH = 4.00? Ka = 1.8×10-5
mol
2. What quantity (moles) of NaOH must be added to 1.0 L of 2.1 M
HC2H3O2 to produce a solution buffered at pH = 5.00? Ka = 1.8×10-5
mol
I really need help! Please show every step of the math no matter
how small! Thank you
what mass of Ca(NO3)2 must be added to 1.0
L of a 1.0 M HF solution to begin precipitation of CaF2.
You may assume no volume change on the addition of
Ca(NO3)2. Ksp for CaF2 = 4.0 x
10-11 and ka for HF=7.2 x
10-4.
How many moles of HCl must be added to 1.0 L of 1.0 M NH3(aq) to
make a buffer with a pH of 9.00? (pKa of NH4+ =9.25)
the answer is 0.64, explain please.
