Calculate the theoretical yield of potassium alum from 1.0000 g of aluminum, assuming that the aluminum is the limiting reagent. First, write the net reaction by adding the net ionic equations that represent the four steps in the synthesis:

Write the net reaction by adding these four reactions and canceling out species that appear on both sides.

Calculate the theoretical yield of potassium alum from 10000 g of aluminum assuming that the aluminum is the limiting reagent First write the net reaction by ad class=

GREETINGS!

Net Reaction is,

[tex]2Al + 8H^+ + 2K^+ + 2OH^- + 4SO_{4}^2- + 22H_{2}O ---> 2KAl(SO_{4})_{2}.12H_{2}O +3H_{2}[/tex]

For total yield,

as the moles are 2 for both aluminium and potash alum if we divide 1 gm by the mass of Al the outcome mole will be 0.3. since the moles are same so potash alum will also have 0.3 mole. Now multiply 0.3 moles by the mass of potash alum that is 474 so the ANSWER FOR THE YIELD WILL BE 142.2 gms

I HOPE THIS HELPS YOU!
