How would you go about solving this pH problem?
What is the $\mathrm{pH}$ of a $0.24\ \mathrm M$ solution of benzylammonium chloride ($\ce{C6H5CH2NH3Cl}$)?
$K_\mathrm b$ for benzylamine is $2.2\times10^{-5}$
Your answer must be within $\pm 0.4\ ...

Why assume a neutral amino acid is given for acid-base reaction?
The questions is:
$1.812\ \mathrm{g}$ of a crystallized α-amino acid ($\mathrm{p}K_\mathrm{a1} = 2.4, \mathrm{p}K_\mathrm{a2} = 9.7$) has a $\mathrm{pH}$ of $10.4$ when dissolved in

Calculate the pH of Na2CO3
Given information:
$K_\mathrm{a}(\ce{H2CO3}) = 4.3 \times 10^{-7}$,
$K_\mathrm{a}(\ce{HCO3-}) = 4.8 \times 10^{-11}$,
${{\ce{[Na2CO3]}=0.20\ \mathrm{M}}}$
This was a question in an exam and I'm ...

How to estimate pH?
How you you calculate/estimate the pH of a solution with 3 components all of different pHs?
Is there a paper describing this?
For example:
0.1M Buffer PCTP at pH 9.5
1.6M Sodium Dihydrogen Phosphate ...
