Stoichiometric Coefficients

Postby Marsenne Cabral 1A » Sun Jan 20, 2019 11:30 am

Will we ever have to calculate the pH of a week acid/ base where the stoiciometric constant is not one, if so, are there any example and how would you go about solving the problem?

I have the same question. I think we would have to factor in the coefficients in the ICE table where we normally account for the change in x. Im not 100% sure though.

I don’t know if we will for this class but basically what you’d do is balance the equation first. Second in the ice table you will want to add/subtract the stoichiometric coefficient times x from your initial value.

I don't know what would be exactly on exams, but it could be possible because the only additional work you would have to do is multiply the x (representing change of concentrations of products) in your ICE table by the coefficient of whichever product has a coefficient that's not 1.

You just have to add the coefficients to the values in the ice table and the rest is exactly the same
