"WebDec 30, 2024 · CH 3 OH acts as a base when reacting with the compound that is more acidic than it, i.e. HCl, HNO 3, H 2 SO 4, etc. This is because a stronger acid has more ability to “donate the proton”. Like when CH 3 OH reacts with HCl, it acts as a base, this is because HCl is stronger acid and has the ability to donate a proton very easily. " - Ch3 2nh2 acid or base
