Unless you pre-leached your wood ash in water and drained it before reacting it with HCL, then it also contains some amounts of Potassium Hydroxide (KOH) in it, hence you were getting that high pH value. That’s the reason why it was called *potash* in ancient times. Thanks for acknowledging in the end that your CaCl2 has some KCL contamination in it. Had you used dry sea weeds to burn, the Sodium contamination would have been higher.
I got the high pH value when I was washing the ashes. I washed most of the soluble salts out but I definitely still had some sort of contamination. Also, thank you for commenting! I enjoy replaying to any comments I get.
