p. 90 right-hand column of
         table, 6th row:		  change 1.14 to 1.13 (should read 1.5 to 1.13)
         next row (starting assess
         separation ...):		  change 1.13 to 1.14
p. 113 equation (4.2): Should be just Cu2S  (not 2Cu2S)
p. 127 question 23 d: Change mercury to silver
p. 157 question 2 (3rd line): after ...82.5% indium add and that oxygen had an atomic weight of 16
p. 316 question 6 The test described does not allow you to determine whether the shiny grey substance is an element or a compound; all it tells you is that it is a pure substance (definite melting point). There are many compounds that are quite stable up to 327oC, so the lack of decomposition does not prove that it is an element. (This was a real boo-boo on my part; sorry.)
p. 321 question 40: 8.2 t (not 8.3 t)
p. 321 question 41: 0.36 t (not 0.26 t)
p. 322 question 13 a:  After RbNO3 insert Cs2SO4

 

 

The following errors occur in the first printing of the fourth edition (2004). They have been corrected in subsequent printings. You can tell which printing your copy of the book belongs to by looking near the top of page iv (opposite the table of contents); if it has a reprint date later than 2004 the errors below will have been corrected.
