x=2.37x10^-3 pH=2.63 is this correct?
Kb= .0876???
does (HA)=58.695. my math was 1g/180.6 * 1/.325L
i see that the equation is pH=pKa+log[base]/[acid]. but i do not know how to get pKa
so where does the Ka=3.3x10^-4 come in? and im lost with what you put in parethesis in ur explanation.
i got 3.2 for my pOH and 6.31x10^-4 for my [OH^-]. after this i am stuck and not sure where to go.
