Now recall that weak basis represent weak electrolytes that only partially dissociate into aqueous ions. Here we're going to say that they require the use of an ice chart. So ICE stands for initial change equilibrium and we use this ice chart to calculate equilibrium amounts.
Now here the units of an ice chart will be in molarity, which remember is moles per liter and we use capital M to represent molarity. And since we're dealing with weak bases, we'd use our base association constant which is KB.
So just keep in mind when it comes to weak basis, because they're weak species, we have to utilize an ice chart in order to tell what their exact equilibrium amounts will be in a given process.
