Given the reaction and information below, each of the values asked for below. (make an I.C.E. table) A(g)+2B(g)↔C(g) You start with 2. atm of each of the reactants in a flask. After a sufficient amount of time the reaction reaches equilibrium at 400K. You...

With the same initial solution of 0.75 moles formate and 0.85 moles formic acid to make a buffer solution. The Ka of formic acid is 1.8x10-4. You add 16g hydrobromic acid to this solution, what is the new pH? I tried making this ice chart but it was wrong...

Thanks i managed to calculate kp as 0.3

Assume a 1L Solution

Could you help with the second question. I tried making this ice chart but it was wrong 16gHBr/80.9119g/mol = 0.1977 mol in 1L ................HCOO^- + H^+ ==> HCOOH I................0.85.............0................0.75 C..........-0.1977....-0.1977.......
