This question has to do with an alum synthesis experiment from aluminum, KOH, and H2SO4. The overall reaction is given in equation (1-1): (1-1) 2Al(s) + 2KOH(aq) + 22H2O(l) + 4H2SO4(aq) ---> 2KAl(SO4)2.12H2O(s) + 3H2(g) Note: we used 0.045 moles of H2SO4 and 0.0175 moles of KOH in the experiment. Question 1: Given that KAl(OH)4 was limiting, how many moles of H2SO4 were actually used to form the maximum possible amount of KAl(SO4)2 (Hint: Moles of Al used in this...

Using stock bottles of CaCl2 and KOH solutions, a student prepared a 1.00L solution mixture which contained, before any reaction occurred, [Ca2+] = 0.075M and [OH–] = 0.085M. After mixing the solution, a precipitate of Ca(OH)2 (s) was formed (reaction occurred in the right-to-left direction). The student then added a further 1.00L of water and stirred; the precipitate disappeared— all the solid had redissolved. Which one of the following is a possible value for the equilibrium constant, Kc, of this...
