Experiment for ideas on possible products for this read 4. The O'Keefe's have 50 gallons of cucumbers for pickling. The 1.5 M KOH solution costs $4.50 per liter, 9 M
H2SO4 solution costs $8 per liter, and ethanol costs $20 per liter. A 50 g jar of alum from the grocery store costs
$8.59. Do you think it's worth the time and trouble for Richard and Diane to make their own alum from
discarded aluminum cans? Explain your answer showing all calculations.
ribute toward lowering the nercent yield of alum.

Because a model would make the investigation easier to understand

Rn in the right answer

The answer is 4 i don't know if its right let me see.

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it
