Knowing she could reduce the candlestick (Au203) from earlier down and obtain pure gold (Au), Anna Littical set upon the chemical reaction. After massing the candlestick
back in the lab, she discovered the candlestick (Au203) had a mass of 475 grams, how
many grams of silver should the chemistry student be able to recover? (Hint: find
percent composition of Au in Au203 first.)
a) 0.268 grams Au
c) 296 g Au
b) 408 grams Agu
d) 393 grams Au

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
