Hi, i am in the 6th grade and I need help with my science project.  First I 
line a glass dish with aluminum foil then I put in pieces of tarnished silver.  
Then i sprinkle 1/4 cup of baking soda over that.  Next i add 1 cup of boiling 
water.  Let it sit for several minutes and the tarnish is gone.  My question 
is, why does this happen?

I would appreciate any help you can give me.

Thank you
