A 1.50 L buffer solution is 0.250 M in HF and 0.250 M in NaF.
Calculate the pH of the solution after the addition of 0.0500 moles
of solid NaOH. Assume no volume change upon the addition of base.
The Ka for HF is 3.5 × 10-4.
A buffer solution that is 0.403 M in
HF and 0.403 M in
NaF has a pH of 3.14.
(1) The addition of 0.01 mol of
H3O+ to 1.0 L of this buffer
would cause the pH to _________increase slightly increase by 2
units decrease slightly decrease by 2 units not change.
(2) The capacity of this buffer for added
H3O+could be increased by
the addition of 0.148 mol_________of the weak acid
of the salt.
Consider these compounds:
A.
CaCrO4...
A 360.0 −mL buffer solution is 0.170 M in HF and 0.170 M in
NaF.
A) What mass of NaOH could this buffer neutralize before the pH
rises above 4.00?
B) If the same volume of the buffer was 0.360 M in HF and 0.360
M in NaF, what mass of NaOH could be handled before the pH rises
above 4.00? I keep getting 1.8 g and 3.5 g, which is wrong.
A 360.0 ml buffer solution is 0.130 mol/L in HF and 0.130 mol/L in NaF.
Part A : what mass of NaOH could this buffer neutralize before the PH rises above 4.00?
Part B: If the same volume of the buffer was 0.370mol/L in NaF, what mass of NaOH could be handled before the pH rises above 4.0?
the Ka of HF is 3.5*10^-4 this is all the information given, I can look up more ka or...
