    $\begingroup$ There is a difference in conductivity between NaOH and KOH due to $\ce{Na+} $ having more spheres of hydration. I would look into conductivity values for the concentration solution you plan to use and see what the difference in conductivity is and determine if it will be an issue. $\endgroup$

  • $\begingroup$ You will get a number of salts when you extract your ashes. Fractional crystallisation could be used to isolate them if it becomes a problem but you need to accept that it is not just one salt in wood fire ash. $\endgroup$
