Problem 18.82

For a number of years it was not clear whether mercury(I) ions existed in solution as Hg1 or as Hg2 21. To distinguish between these two possibilities, we could set up the following system: Hg(l) 0 soln A 0 0 soln B0 Hg(l) where soln A contained 0.263 g mercury(I) nitrate per liter and soln B contained 2.63 g mercury(I) nitrate per liter. If the measured emf of such a cell is 0.0289 V at 18C, what can you deduce about the nature of the mercury(I) ions?

Step-by-Step Solution:
Step 1 of 3

Chapter 5 Notes I. physical vs chemical changes A. physical: composition remains the same, change of state B. chemical: new substance is formed C. chemical reactions: involve chemical changes, atoms are rearranged II. chemical reactions- use formulas and symbols to represent chemical reaction “recipe” A. reactants on the left side of the equation, “ingredients” B. products on the right side of the equation, “cake” C. arrows  separates reactants from products D. reactants must equal your products = balanced equation E. to balance an equation: 1.each individual compound must be written correctly before balancing 2. coefficients are used (numbers in front of the compound/element) 3. number of atoms of each element must be the same on both sides 4. coefficients must be in the lowest terms 5. watch out for diatomic elements BrINClHOF 6. practice F. symbols used= table 5.1 III. types of reactions A. combination/composition/synthesis: 2 or more elements or simple compounds to form one product A+B AB B. decomposition reaction: compound splits into two or more simple elements AB A+B C. single replacement: one element replaces another in a compound A+BC  B+AC D. double replacement: two compounds reacting, negative and positive ions switch places AB+CD  AD+CB E. combustion: carbon and hydrogen react on the presence of oxygen, produc
