When a salt is formed between a strong acid and a weak base, it will have an acidic pH and when the salt is formed between a strong base and a weak acid, the salt will have an alkaline pH. So let's our reaction here. Explain. There was no strong acid or strong base for the weak species to react with, so we knew that we only had to set up an aqueous equilibrium between the conjugate acid/base pair and use Henderson Hasselbalch to find pH. One "rule of thumb" that I learned is if your x ends up being larger than 5% of your starting value you need to solve the quadratic. So Ka is equal to: concentration .25, and if that's the case, if this is an extremely small number, we can just pretend like Is an aqueous solution with pOH = 5.12 acidic, basic, or neutral?
